The utility for counting all possible chess moves (based on the perft function).

Features

• counting all possible moves:
  • parameters:
    • 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);
    • position;
    • color that moves first;
    • analysis deep;
• profiling:
  • targets:
    • CPU usage;
    • memory usage;
  • storing the results to files.
