--- layout: archive title: Zulip Chat Archive permalink: /stream/113489-new-members/topic/Why.20is.20is_subfield.20not.20a.20Prop.3F.html ---
I want to define
variables {L : Type} def subfields : set (set L) := {K' : set L | is_subfield K'}
But I run into a problem because is_subfield
is somehow a Type
, not a Prop
. Why is this/how is this possible, and how can I fix the problem?
By mistake. It should be changed.
Do you know how I can circumvent the problem?
you can use nonempty (is_subfield K')
You can now also just update mathlib :-)

Hmm, InfinityWard made a massive step forward to come even with DICE. Their new game, Call of Duty: Ghosts, is with it's new engine a better looking game. The trailer somehow gives me goosebumps.. The time when I was addicted to Call of Duty is over, but this reminds me of the game it supposed to be. An award winning game with loads of good gameplay.
Just for the record, I played Modern Warfare 1 and 2.
Back to Call of Duty: Ghosts. One thing for sure, InfinityWard have made bigger improvements with Ghosts, than DICE did with BF4. Here's the trailer.
http://www.youtube.com/watch?v=Zxnx3W-HA18
Tell me what you guys think of it.
One thing I like about CoD:G - LEAN!
FFs COD is an arcade game and they added this tactical feature. Why can't DICE implement it?
Anyways - graphic on BC2-BF3 level, nothing new.

Pre-rendered trailers are always nice looking. But without actual game play being shown, nothing is known for sure.
I guess we'll have to wait for E3.

Everyone thought that after MW2, Black ops will have got such great graphics. After black ops, though much people thought hat MW3 will have >> the << new great graphics experience.
One thing for sure, InfinityWard have made bigger improvements with Ghosts, than DICE did with BF4.
Wow, it's so hard to improve Black Ops 2 with his great graphix.
Anyway, at the Xbox one event, Activision talked about "dynamic experiences". Huh, sounds like Frostbite destruction? I remember that they've said at the release of MW3 or BO2, that destruction doesn't work with the "typical" gameplay of CoD. Fuckin copycats. They realized that battlefield took CoD doggy.

I'll wait some gameplay video. It didn't surprise me too much, especially the character models (BF4 wins hands down). The lean feature is nothing new (see Call of Duty 1, UO, 2, 4).

My sarcasm radar seems to not work in this case, i dont know what to think Meaurk.
Somebody will buy this game?
For me it's 50/50 - Dedicated Server is the main reason why i don't like the prev. titles.

Free dedicated server soft is the only thing CoD series did right, anyone can host a server.
Server finding thingy? Whats battlelog then? What about preBF3? Same thing.

I don't mean with "server host" thingy the server browser list in BF or the server list in COD.
But in the last COD's you didn't had any of that. You just get randomly assigned to a match, the is hosted by a user itself (anyone is randomly the host). You don't have the choice on which "host" you can join.

Dedicated server that a player can open/host is the best what a multiplayer can have. That was the best in the "old school" shooters. Now everybody try to make money from the cow (the community).
Now is COD Ghosts it seems like that Dedicated Server come back.

That was the IWnet thing and yes, that wasn't so cool.

Buy? i dont think so, well, i won't buy BF4 neither due to actual rig limitations (it's not much enjoyable in my machine but it's barely playable.), in fact, i feel like this:
http://i.imgur.com/hSC6wCF.gif
If for some reason someone gifts COD to me i will play it, I don't care if it's worst than BF4, i'm pretty sure my rig will be capable of handle this, and that's more than enough for me to play it, also if i can create a server like in other games (with a software) i may use the dedicated remote server i have access to
only
host scrims and play without lag.
the dedicated server is part of the game server our clan sponsor has, if not, i would donate it for BBLog stuff. Only I and our sponsor have access to it due to the fact i do some work for them, maybe i'll get some pay in the future, not much, but for me every penny is worth it. :D.

Is that the server's connection, or is that on your personal machine.?

**kamikaze packet**: n.
The ‘official’ jargon for what is more commonly called a `*Christmas
tree packet* <../C/Christmas-tree-packet.html>`__.
`*RFC* <../R/RFC.html>`__-1025, *TCP and IP Bake Off* says:
10 points for correctly being able to process a “Kamikaze” packet
(AKA nastygram, christmas tree packet, lamp test segment, et al.).
That is, correctly handle a segment with the maximum combination of
features at once (e.g., a SYN URG PUSH FIN segment with options and
data).

The calls are coming in from engineers who are having problems with either the Trend software or hardware. With my background in software support I was brought onto the team to primarily focus on supporting the new supervisor software IQVision which is based on the N4 Tridium platform. With my knowledge of databases I also found my self investigating, fixing and writing SQL scripts for the legacy supervisor tool 963 which has an SQL Server 2012 back end.

Contains core system components that perform the evolution process.
Defines modules for evaluating fitness as well as the generic definition of a fitness function for programs in the system. A fitness function is the main driving force for determining the best program in a population of individuals.
A set of built-in fitness functions are also provided from the core library.
Provides an abstraction for the primary model of evolution. The main LGP algorithms are implemented in three variants:
SteadyState
: The classic LGP algorithm.MasterSlave
: The classic LGP algorithm, but performs evaluation in parallel.IslandMigration
: Runs independent instances of the classic LGP algorithm on subsets of an overall population
and uses an island migration technique to share individuals between populations. Contains interfaces and implementations for the primary evolutionary operators available to the system:
Provides a set of interfaces and implementations for performing aggregate evolution (training). It is often desirable to build and evaluate a model multiple times in succession/parallel, which the training abstractions allow.

Engineering is a stream of education which involves the application of Science, Technology and Mathematics to innovate, design, develop and maintain machines, structures, software, hardware and systems & processes. This field offers a range of career opportunities across all industries, making it one of the most sought after course pursued by students after Class XII, especially those from the Science stream. Students planning to study Engineering in India can choose from nearly 100 specialisations, with Computer Science Engineering, Civil Engineering, Electronics Engineering, Electrical Engineering and Mechanical Engineering being some of the most popular ones. According to a 2018-19 report of the All India Survey of Higher Education (AISHE) powered by the Ministry of Human Resource and Development (MHRD), Engineering is the third major stream with 37.70 lakh students enrolled at the undergraduate level. The share of male student enrolled in Engineering and Technology is 71.1 per cent where female enrolment is 28.9 per cent.
