What is it?

An Oware Abapa artificial intelligence game engine.

Aalina (a.k.a. Aualé) is a strong Oware playing artificial intelligence engine. It communicates with a Graphical User Interface through an adapted version of the Universal Chess Interface protocol. This mancala engine is thus usually invoked by a GUI, such as Aualé, which is the official interface for this engine, but can also be played on the terminal.

Demo

Its features include:

  • Command line interface
  • Plays mancala following the popular Abapa ruleset
  • Completely configurable through the UCI protocol
  • Includes a set of engine optimization tools

Implementation details:

  • Negamax search
  • Iterative deepening
  • Principal variation search
  • Optimized evaluation heuristics
  • Minimal perfect hashing of positions
  • Endgame tablebases (12 seeds or less)
  • Automatically built openings book
  • Two-tier transposition table with aging
  • Simple time management
  • UCT based openings book trainer
  • Complete UCI protocol support
  • Optional UCT/MCTS search

Command line tools:

  • UCI protocol service
  • UCI protocol shell interface
  • Automatic openings book trainer
  • Command line playing interface
  • Engine benchmark, perft and divide
  • Tournament runner
  • Basic tests
