I'm working with multiple big mutually defined inductive types (I'm trying to formalize a language with up to 7 different syntactic sorts). This works okay, but when I try to define corresponding recursive functions, Lean informs me that it has failed to prove recursive application is decreasing, well founded relation
.  Is there a simple workaround? Thanks in advance!
https://github.com/leanprover-community/mathlib/blob/master/docs/extras/well_founded_recursion.md
I guess I am in the third case, where I need to define my own well-founded relation. The document suggests
The easiest way to define a well founded relation is using a function to the natural numbers.
This indeed solves the example above, but for my bigger example, the obvious candidate is the size of the term. However, for this I need to define 3+ mutually recursive functions, again causing the error above. What am I missing? I attach the full example. syntax.lean
Generally speaking, mutual def
is pretty fragile, and things often go wrong.
Thank you for the advice, but unfortunately, it does not generalize to my case. I guess the simple example I gave was misleading. What I have are say mutually recursive types T1
, T2
and T3
and I need to define functions size1 : T1 \to N
, size2 : T2 \to N
, size3 : T3 \to N
(as a first step in getting a well-founded relation). I tried avoiding mutual def
by defining a single function size : T1 \oplus T2 \oplus T3 \to N
, but I get the same error.

Is there a better way of defining this function aside from listing all the possible 8 x 10 x 2 = 160 cases? I guess one can be smart with auxiliary functions, but probably that again leads to the well-foundedness issues?
@Matija Pretnar Yes, the declaration is slightly more ugly than three separate functions, but you do not need any more cases than you would have otherwise.
Just use a match
statement to break off how to generate the three separate outputs
Like, a match for each of T1
, T2
, and T3
(or however many there actually are).
Definitely there should be no duplication like you proposed.
Most of the time, for me anyway, writing everything like this just works out of the box.
https://github.com/leanprover-community/mathlib/blob/master/docs/extras/well_founded_recursion.md
is where you have to go to fix further problems you then have
@Keeley Hoek Many thanks! You had me scared there for a moment :grinning: Do you by any chance have an example lying around so I can adapt it to my case?
Sorry, not really. Here is sort-of an example:
https://github.com/leanprover-community/mathlib/pull/1274/files#diff-5d76d023ea3a78d10ca04f9fa501e572R187
Ideally le
and lt
would be defined mutually, but you can see in that case that they are defined together. A using_well_founded
at the end there is in fact required to make things actually work, but this seems about the easiest way forward, for example.
I'll give it a try, thanks again!
I have played around with it a bit and I would guess that the problem is in the fact that the type A + B + C
is actually A + (B + C)
(and the same problem probably persists with products?). As such, if you have b : B
and cons b : A
if you put them in the sum they become sum.inr (sum.inl b)
and sum.inl (cons b)
, both having .sizeof
(which is the default ordering it tries to use as far as I can tell) of 2 despite b
being a subterm of cons b
.
Example:
mutual inductive A, B, C with A : Type u | base : A | cons : C → A with B : Type u | cons : A → B with C : Type u | cons : B → C mutual def adepth, bdepth, cdepth with adepth : A → ℕ | A.base := 1 | (A.cons c) := 1 + cdepth c with bdepth : B → ℕ | (B.cons a) := 1 + adepth a with cdepth : C → ℕ | (C.cons b) := 1 + bdepth b
The above code complains that it cant prove 2 < 2
in the case | (A.cons c) := 1 + cdepth c
.
This can then be kinda fixed by introducing a new type t(riple)sum
.
inductive tsum | first : A → tsum | second : B → tsum | third : C → tsum def depth : tsum → ℕ | (tsum.first A.base) := 1 | (tsum.first (A.cons c)) := 1 + depth (tsum.third c) | (tsum.second (B.cons a)) := 1 + depth (tsum.first a) | (tsum.third (C.cons b)) := 1 + depth (tsum.second b)
and the code seems to work for now.
But could one perhaps construct a better sizeof
function for a specific sumtype?
So something like
def correct_size : A+B+C → ℕ | (sum.inl a) := A.sizeof a | (sum.inr (sum.inl b)) := B.sizeof b | (sum.inr (sum.inr c)) := C.sizeof c
and then use this as the measure? I have failed to find a way to insert this into the using_well_founded
even with the help of
https://github.com/leanprover-community/mathlib/blob/master/docs/extras/well_founded_recursion.md
If I made any kind of wrong assumptions or conclusions please let me know.
correct_size
is not correct, because you are depending on the sizeof instance of A which is broken (you have to use correct_size
to define it, meaning that this function is mutually recursive with a typeclass instance)
The best way to solve this issue is to rewrite the mutual inductive as a regular inductive and use plain induction

The Fayoumis are a very old breed, originating in Egypt. They were named for the Faiyum Governorate southwest of Cairo and west of the Nile. Fayoumis are a hardy breed and particularly well suited to hot climates. The breed, through poultry genetics research and anecdotal reports, is thought to be especially resistant to viral and bacterial infections. They are also very good foragers, and if left to their own devices on a free range basis they can fend for themselves in a nearly feral manner. Fayoumi hens are good layers of small, off-white eggs. They are not given to broodiness as pullets, but can be when they reach two or three years of age. The breed is fast to mature, with hens laying by four and half months, and cockerels crowing at five or six weeks.

Class AgentSet
Family Class is the basis class from which we build the families of agents.
Families are the main structures of the system. It consists in a table of Agents, a list of ids and some methods to manipulate the agents. self.agents is a table 'object_id: object' and we use it to find an element quickily.
Functions
- Instance:clone_n (num, agent, funct)
-
This function creates a number of clones of an agent and, if a function is gived as parameter, it applies a function to them. It uses the auxiliar function "clone" to obtain the clones and the auxiliar function "searchfreeid" to give a new id to the clones.
Usage:
Agents1:clone_n(1, agent, function(x) x.color = 'red' end) -- If we just want to create same agents, we can call this function without the last parameter: Agents1:clone_n(3, agent)
- Instance:exists (pred)
-
Returns true if any agent in the family validates a predicate.
See also:
Usage:
local response = A_family:exists( function(x) x.label ~= '' end )
- Instance:all (pred)
-
Checks if all agents in a family validates a condition.
See also:
Usage:
A_family:all(function(ag) ag.label == '' end)
- Instance:is_in (agent)
-
Checks if an agent is member of the AgentSet.
See also:
Usage:
A_family:is_in(agent)
- Instance:others (agent)
-
Given an agent, it returns all the other agents in the AgentSet.
See also:
Usage:
Instance:others(agent)
- Instance:one_of_others (agent)
-
Given an agent, it returns,randomly, one of the other agents in the family, or nil if there is no other agent.
See also:
Usage:
Instance:one_of_others(agent)
- Instance:with (pred)
-
Filter function.
See also:
Usage:
local lower_agents = Agents:with( function(ag) return ag:ycor() < 2 end )

See also:
Usage:
local random_alive_agent = A_family:one_of()
- Instance:n_of (n)
-
Selects and returns n random alive agents of the AgentSet. If the number of agents of the family is minor that n this function returns an error message.
See also:
Usage:
local three_agents = A_family:n_of(3)
- Instance:up_to_n_of (n)
-
This function selects n random agents of a AgentSet. When there are fewer than n agents in the family, this function returns all agents in the AgentSet.

https://en.wikipedia.org/wiki/Ising_model
The energy of a spin configuration S = {S_i} is given by H(S) = -J \sum_ij S_i S_j
The Metropolis-Hastings algorithm first chooses 'selection probabilities' g(u,v), the probability that state v is selected by the algorithm out of all states, given that one is in state u. g(u,v) must be selected such that ergodicity is met. Then the algorithm uses 'acceptance probabilities' A(u,v) so that detailed balance is satisfied. In thermal equilibrium a system's energy only fluctuates within a small range. This is the motivation behind the concept of 'single-spin-flip dynamics', which states that in each transition, we will only change one of the spin sites on the lattice.
Specification g(u,v) = 1 / (the number of sites on the lattice), [assumption] g(u,v) = g(v,u), P(u,v) = g(u,v) A(u,v), Warning P(u,v) != P(v,u). Detailed balance tells us that the following equation must hold: P(u) P(u,v) = P(v) P(v,u). P(u,v) / P(v,u) = P(v) / P(u) = exp(-β (H(v)-H(u))) [Z is cancelled], P(u,v) / P(v,u) = A(u,v) / A(v,u). We want to select A(), the larger A(u,v) or A(v,u) will be 1. A(u,v) = [ exp(-β (H(v)-H(u))), if H(v)-H(u) > 0, [ 1 otherwise.
The basic form of the Metropolis algorithm is as follows: (1) Pick a spin site using selection probability g(u,v) and calculate the contribution to the energy involving this spin. (2) Flip the value of the spin and calculate the new contribution. (3) If the new energy is less, keep the flipped value. (4) If the new energy is more, only keep with probability exp(-β (H(v)-H(u))). (5) Repeat.
Spin lattice L = np.ones((x, y), dtype=np.int64) # ordered system, energy = -2*L.size L = np.empty((x, y), dtype=np.int64) # uninitialized spins L.shape # return (x, y) L.size # the number of sites on the lattice (x*y) L.sum() # total magnetization If spin = L[i,j], then (periodic boundary conditions) neighbors = ( L[(i+1) % x, j] + L[(i+x-1) % x, j] + L[i, (j+1) % y] + L[i, (j+y-1) % y] ) After flip [prob > random.random()] L[i, j] = -spin # the 'spin' variable keeps the old value energy += 2 * spin * neighbors magnet -= 2 * spin

Users may want to write a layered library on top of an existing MPI implementation, and this library may have its own set of error codes and classes. An example of such a library is an I/O library based on MPI, see Chapter I/O on page I/O . For this purpose, functions are needed to:
| MPI_ADD_ERROR_CLASS(errorclass) | |
| OUT errorclass | value for the new error class (integer) |
int MPI_Add_error_class(int *errorclass)
MPI_ADD_ERROR_CLASS(ERRORCLASS, IERROR)
INTEGER ERRORCLASS, IERROR
{ int MPI::Add_error_class() (binding deprecated, see Section Deprecated since MPI-2.2
) }
Creates a new error class and returns the value for it.
To avoid conflicts with existing error codes and classes, the value is
set by the implementation and not by the user.
( End of rationale.)
A high-quality implementation will return the value for a new
errorclass in the same deterministic way on all processes.
( End of advice to implementors.)
Since a call to MPI_ADD_ERROR_CLASS is local, the same
errorclass may not be returned on all processes that make
this call. Thus, it is not safe to assume that registering a new
error on a set of processes at the same time will yield the same
errorclass on all of the processes. However, if an
implementation returns the new errorclass in a deterministic
way, and they are always generated in the same order
on the same set of processes (for
example, all processes), then the value will be the same. However,
even if a deterministic algorithm is used, the value can vary across
processes. This can happen, for example, if different but overlapping
groups of processes make a series of calls. As a result of these issues,
getting the ``same'' error on multiple processes may not cause the
same value of error code to be generated.
( End of advice to users.)
The value returned by the key
MPI_LASTUSEDCODE will not change unless the user calls a
function to explicitly add an error class/code. In a multi-threaded
environment, the user must take extra care in assuming this value has
not changed.
Note that error codes and error classes are not necessarily dense. A user may not assume that each error class below MPI_LASTUSEDCODE is valid.
( End of advice to users.)
int MPI_Add_error_code(int errorclass, int *errorcode)
MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR)
{ int MPI::Add_error_code(int errorclass) (binding deprecated, see Section Deprecated since MPI-2.2
) }
Creates new error code associated with
errorclass and returns its value in errorcode.
To avoid conflicts with existing error codes and classes, the value
of the new error code is set by the implementation and not by the
user.
( End of rationale.)
A high-quality implementation will return the value for a new
errorcode in the same deterministic way on all processes.
( End of advice to implementors.)
int MPI_Add_error_string(int errorcode, char *string)
MPI_ADD_ERROR_STRING(ERRORCODE, STRING, IERROR)
{ void MPI::Add_error_string(int errorcode, const char* string) (binding deprecated, see Section Deprecated since MPI-2.2
) }
Associates an error string with an error code or class.
The string must be no more than MPI_MAX_ERROR_STRING
characters long. The length of the string is as defined in the
calling language.
The length of the string does not include the null terminator in C or C++.
Trailing blanks will be stripped in Fortran.
Calling MPI_ADD_ERROR_STRING for an errorcode
that already has a string will replace the old string with the new
string. It is erroneous to call MPI_ADD_ERROR_STRING for
an error code or class with a value leq constiMPI_ERR_LASTCODE.
If MPI_ERROR_STRING is called when no string has been set,
it will return a empty string (all spaces in Fortran, "" in C and
C++).
Section Error Handling
on
page Error Handling
describes the methods for creating
and associating error handlers with communicators, files, and windows.
int MPI_Comm_call_errhandler(MPI_Comm comm, int errorcode)
MPI_COMM_CALL_ERRHANDLER(COMM, ERRORCODE, IERROR)
{ void MPI::Comm::Call_errhandler(int errorcode) const (binding deprecated, see Section Deprecated since MPI-2.2
) }
This function invokes the error handler assigned to the communicator
with the error code supplied.
This function returns MPI_SUCCESS in C and C++ and the same
value in IERROR if the error handler was successfully called
(assuming the process is not aborted and the error handler returns).
Users should note that the default error handler is
MPI_ERRORS_ARE_FATAL. Thus, calling
MPI_COMM_CALL_ERRHANDLER will abort the comm
processes if the default error handler has not been changed for this
communicator or on the parent before the communicator was created.
( End of advice to users.)
int MPI_Win_call_errhandler(MPI_Win win, int errorcode)
MPI_WIN_CALL_ERRHANDLER(WIN, ERRORCODE, IERROR)
{ void MPI::Win::Call_errhandler(int errorcode) const (binding deprecated, see Section Deprecated since MPI-2.2
) }
This function invokes the error handler assigned to the window
with the error code supplied.
This function returns MPI_SUCCESS in C and C++ and the same
value in IERROR if the error handler was successfully called
(assuming the process is not aborted and the error handler returns).
As with communicators, the default error handler for windows is
MPI_ERRORS_ARE_FATAL.
( End of advice to users.)
int MPI_File_call_errhandler(MPI_File fh, int errorcode)
MPI_FILE_CALL_ERRHANDLER(FH, ERRORCODE, IERROR)
{ void MPI::File::Call_errhandler(int errorcode) const (binding deprecated, see Section Deprecated since MPI-2.2
) }
This function invokes the error handler assigned to the file
with the error code supplied.
This function returns MPI_SUCCESS in C and C++ and the same
value in IERROR if the error handler was successfully called
(assuming the process is not aborted and the error handler returns).
Unlike errors on communicators and windows, the default behavior for files is to have
MPI_ERRORS_RETURN.
( End of advice to users.)
Users are warned that handlers should not be called recursively with
MPI_COMM_CALL_ERRHANDLER,
MPI_FILE_CALL_ERRHANDLER, or
MPI_WIN_CALL_ERRHANDLER. Doing
this can create a situation where an infinite recursion is created.
This can occur if MPI_COMM_CALL_ERRHANDLER,
MPI_FILE_CALL_ERRHANDLER, or
MPI_WIN_CALL_ERRHANDLER is called
inside an error handler.
Error codes and classes are associated with a process. As a result,
they may be used in any error handler. Error handlers should be
prepared to deal with any error code
they are
given. Furthermore, it is
good practice to only call an error handler with the appropriate
error codes. For example, file errors would normally be sent to the
file error
handler.
( End of advice to users.)

Advice
to implementors.
Advice to users.
The value of MPI_ERR_LASTCODE
is a constant value and
is not affected by new user-defined
error codes and classes.
Instead, a predefined attribute key MPI_LASTUSEDCODE is
associated with
MPI_COMM_WORLD. The attribute value corresponding to this key
is the current maximum error class including the user-defined ones.
This is a local value and may be different on different processes.
The value returned by this key is always greater than or equal to
MPI_ERR_LASTCODE.

The web serves as a collection of documents with many pieces.
There are approximately 30 billion pages and hyperlinks are throughout. A variety of document types and hyperlinks included within HTML.
These include:
HTML is the heart of the WEB and is composed of:
Tags are primarily composed of opening and closing tags. However, there are tags called 'void' which do not require a closing tag.
Failing to properly close a tag may result in everything following the opening tag to assume that attribute of that tag. For example, if one were to use an opening tag of "em" and fail to close that tag, everything from the opening tag forward would be shown in italics.
Sample tags include:
Attributes are properties of HTML and used properly, create powerful pages.
Attributes include:
Anchor tags use the "href" attribute while image tags use the "src" attribute.
Computers have yet to reach a full state of articial intelligence and currently posess the proberties applied by a programmer.
Inline elements include:
Block elemeents include:
Addtionally these block elements may be considered 'container' elements and have content.
The basic structure contans the document type, a header with a title, and the body where the
content is displayed. It is important to remember to match all required opening and closing tags.

Rosie is re-launching the Thermo Kennel at the Mystery Creek Fieldays. If she succeeds, Tony’s vision of every working dog having a hygienic, warm and durable kennel will be realised. Her message to dog owners - in the words of the late Tony Prentice – “don’t give your dog a bone, give him a decent home!”


Installing
By default Meson will not install anything. Build targets can be installed by tagging them as installable in the definition.
project('install', 'c')
shared_library('mylib', 'libfile.c', install : true)
There is usually no need to specify install paths or the like. Meson
will automatically install it to the standards-conforming location. In
this particular case the executable is installed to the bin
subdirectory of the install prefix. However if you wish to override the
install dir, you can do that with the install_dir
argument.
executable('prog', 'prog.c', install : true, install_dir : 'my/special/dir')
Other install commands are the following.
install_headers('header.h', subdir : 'projname') # -> include/projname/header.h
install_man('foo.1') # -> share/man/man1/foo.1.gz
install_data('datafile.cat', install_dir : join_paths(get_option('datadir'), 'progname')) # -> share/progname/datafile.dat
Sometimes you want to copy an entire subtree directly. For this use case there is the install_subdir
command, which can be used like this.
install_subdir('mydir', install_dir : 'include') # mydir subtree -> include/mydir
Most of the time you want to install files relative to the install
prefix. Sometimes you need to go outside of the prefix (such as writing
files to /etc
instead of /usr/etc
. This can be accomplished by
giving an absolute install path.
install_data(sources : 'foo.dat', install_dir : '/etc') # -> /etc/foo.dat
Custom install behaviour
Sometimes you need to do more than just install basic targets. Meson makes this easy by allowing you to specify a custom script to execute at install time. As an example, here is a script that generates an empty file in a custom directory.
#!/bin/sh
mkdir "${DESTDIR}/${MESON_INSTALL_PREFIX}/mydir"
touch "${DESTDIR}/${MESON_INSTALL_PREFIX}/mydir/file.dat"
As you can see, Meson sets up some environment variables to help you write your script (DESTDIR
is not set by Meson, it is inherited from the outside environment). In addition to the install prefix, Meson also sets the variables MESON_SOURCE_ROOT
and MESON_BUILD_ROOT
.
Telling Meson to run this script at install time is a one-liner.
meson.set_install_script('myscript.sh')
The argument is the name of the script file relative to the current subdirectory.
DESTDIR support
Sometimes you need to install to a different directory than the install prefix. This is most common when building rpm or deb packages. This is done with the DESTDIR
environment variable and it is used just like with other build systems:
$ DESTDIR=/path/to/staging/area ninja install
The results of the search are
