go-chess-comparator

The utility for comparing the generation of all possible chess moves by different board representations.

Features

• comparing the generation of all possible chess moves by different board representations:
  • representing the board:
    • as an associative array of pieces with their positions as keys;
    • as a plain array of pieces with exact correspondence array indices to piece positions;
    • as a set of integers corresponding to a particular combination of piece color and type, and where each bit corresponds to a particular piece position (so-called a bitboard);
  • parameters:
    • position;
    • color that moves first;
    • comparing mode:
      • depth-first;
      • breadth-first;
    • analysis deep.

Installation

$ go install github.com/thewizardplusplus/go-chess-models/cmd/go-chess-comparator@latest

Usage

$ go-chess-comparator -h | -help | --help
$ go-chess-comparator [options]

Options:

• -h, -help, --help — show the help message and exit;
• -fen STRING — board in Forsyth-Edwards Notation (default: rnbqk/ppppp/5/PPPPP/RNBQK, i.e., Gardner's minichess);
• -color {black|white} — color that moves first (default: white);
• -mode {depth-first|breadth-first} — comparing mode (default: depth-first);
• -deep INTEGER — analysis deep (should be greater than or equal to zero; default: 5).
