'''ChessCore''', (ChessBin.com)<br/>
a chess engine by [[Adam Berent]], written in [[C sharp|C#]].
The ''ChessBin.com'' chess engine was documented in a blog format, and has been converted to cross-platform [https://en.wikipedia.org/wiki/.NET_Core .NET Core] dubbed '''ChessCore''', [[:Category:Open Source|open source]] under the [[Massachusetts Institute of Technology#License|MIT License]] published on [https://en.wikipedia.org/wiki/GitHub GitHub] <ref>[https://github.com/3583Bytes/ChessCore GitHub - 3583Bytes/ChessCore: Chess Engine Implemented in .net core]</ref>.
The program makes heavy use of the .NET Core [https://en.wikipedia.org/wiki/Garbage_collection_(computer_science) garbage collector] (GC)
<ref>[https://www.tutorialspoint.com/dotnet_core/dotnet_core_garbage_collection.htm .NET Core - Garbage Collection - Tutorialspoint]</ref> and is mentioned as buggy in [[Ron Murawski|Ron Murawski's]] engine list <ref>[http://computer-chess.org/doku.php?id=computer_chess:wiki:lists:chess_engine_list Chess Engine List] from [[Ron Murawski|Ron Murawski's]] [http://computer-chess.org/doku.php?id=home Computer-Chess Wiki]</ref>.

One sample of ChessCore's extensive GC usage demonstrates its [[Alpha-Beta]] search - at each [[Node|node]], it allocates the [[Move List|move list]] and each generated [[Moves|move]] on the [[Data#Dynamic Data|heap]] <ref>[https://github.com/3583Bytes/ChessCore/blob/master/ChessCoreEngine/Search.cs#L406 ChessCore/Search.cs at master · 3583Bytes/ChessCore · GitHub - private static List<Position> EvaluateMoves(Board examineBoard, byte depth)]</ref>:
For some reason, internal class ''position'' encapsulates the move.

... Score move, killers, etc ..
