kandi X-RAY | FEN Summary
Fairness is essential for human society, contributing to stability and productivity. Similarly, fairness is also the key for many multi-agent systems. Taking fairness into multi-agent learning could help multi-agent systems become both efficient and stable. However, learning efficiency and fairness simultaneously is a complex, multi-objective, joint-policy optimization. Fair-Efficient Network (FEN) is proposed to address these difficulties. FEN also stands for 「分」 in chinese, means "share.". FEN is a novel hierarchical reinforcement learning model to learn both fairness and efficiency driven by fair-efficient reward. FEN consists of one controller and several sub-policies, where the controller learns to optimize the fair-efficient reward, one sub-policy learns to optimize the environmental reward, and other sub-policies learn to provide diverse fairness behaviors guided by the derived information-theoretic reward. FEN can learn and execute in a fully decentralized way, coordinated by average consensus. FEN easily learns both fairness and efficiency and significantly outperforms baselines in a variety of multi-agent scenarios. The code is the implementations of FEN in the three scenarios, i.e., job scheduling, the Matthew effect and manufacturing plant, presented in the paper Learning Fairness in Multi-Agent Systems. The following illustrates the different behaviors of FEN agents (left) and Independent agents (right) in job scheduling.

QUESTION
I am currently developing a chess engine in C++, and I am in the process of debugging my move generator. For this purpose, I wrote a simple perft() function:
ANSWER
Answered 2022-Feb-22 at 01:14This is how you would like to debug your move generator using perft.
- Given startpos as p1, generate perft(3) for your engine and sf. (you did that)
- Now check any move that have different nodes, you pick a2a3. (you did that)
- Given startpos + a2a3 as p2, generate perft(2) for your engine and sf. (you partially did this)
- Now check any move that have different nodes in step 3. Let's say move x.
- Given startpos + a2a3 + x as p3, generate perft(1) for your engine and sf.
Since that is only perft(1) by this time you will be able to figure out the wrong move or the missing move from your generator. Setup that last position or p3 on the board and see the wrong/missing moves from your engine compared to sf perft(1) result.

Answered 2022-Feb-16 at 22:57I simply added the code for the buttons at the bottom of your code. This code attaches event handlers to the start and clear buttons, so it could be placed anywhere outside of a function. Here's some code to display the two buttons below the board. I also added some code to run the code inside the code snippet.

I have this very easy program which I want to display one random line from a file each time I click on the Button.
Problem is a new line is display at startup of the program, but nothing happens when I click the button, can someone explain me why ?

Answered 2022-Jan-27 at 12:56As stated in one of the comments (by @matszwecja), your entree() function doesn't really do anything appart from returning a value.
Nothing in your code updates the actual label. Try something like this :
QUESTION
When I test my code with the position r1bqkbr1/pp2pppp/2n1p2n/2p5/3P4/7N/PPP2PPP/RNBQKB1R w KQq - 3 6 the code below outputs ValueError: illegal uci: 'd8d7' in r1bqkbr1/pp2pppp/2n1p2n/2p5/3P4/7N/PPP2PPP/RNBQKB1R w KQq - 3 6 when run. The issue seems to be that the board is not updating after I push a new move (it still generates legal moves thinking it is black to move, when it is actually white to move). How do I fix this?

...ANSWER
Answered 2022-Jan-15 at 02:40There is no way to use a wildcard in the field name in a query.
To implement this use-case, you can:
- Either create a top-level field with all
fenvalues (using anarray-union), and query witharray-containsagainst that field. - Or put the
_rEG,_ASand_BSSAin documents in a dedicated subcollection, and query against that with a collection group query.
QUESTION
I made a chess Program.js that is not working fine;
I want to generate the FEN out of the board list that looks like this
...ANSWER
Answered 2022-Jan-06 at 01:06Your solution correctly makes use of the modulus operator to determine the file, but does not take into consideration that the ranks are added to the FEN beginning with the last row in the board array. Subsequently, the solution is easier with a pair of nested for loops, with the outer loop handling the rank and the inner loop handling the file.
Note how the rank iterates from 7 to 0 to facilitate the proper order of ranks in the resulting FEN.

I have the following fen RNBK1B1R/PPPPQPPP/5N2/3pP3/4p1p1/2n2n2/ppp2p1p/r1bkqb1r b which is generated from a image recognition technique. This fen is based on a flipped board such that the black pieces are at the bottom. When I check the legal_moves, seems like the trajectory of my pieces are backwards. Is there any way to control the direction of my pieces?
Here's the image of the board along with legal moves -

QUESTION
I am working on a chess engine for some time now. For improving the engine, I wrote some code which loads chess-positions from memory into some tuner code. I have around 1.85B fens on my machine which adds up to 40Gb (24B per position).
After loading, I end up with a vector of positions:
...ANSWER
Answered 2021-Nov-17 at 08:59There is a tradeoff to be made: Shuffling a a std::vector of indices can be expected to be cheaper than shuffling a std::vector at the cost of an indirection when accessing the Positions via shuffled indices. Actually the example on cppreference for std::iota is doing something along that line (it uses iterators):

Install FEN
You can use FEN like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
