Sirius 0.8.0 is tbs software developed by Henrik ?hman.
Sirius is a program for playing the game of othello. The program includes an AI (Artificial Intelligence) opponent which plays at a very challenging level and is actually quite hard to beat. The AI opponent's strength can therefore be adjusted in several ways to give you a suitable opponent.

The AI opponent uses a plain alpha-beta search with hashing to figure out which move to make. To be able to tell a god position from a bad one, it uses a pattern based evaluation function.

The pattern used is the 9 discs surrounding each corner and the 8 discs creating the edge of the board. The evaluation function also takes mobility, potential mobility and parity into count. For the initial 9 moves the AI opponent optionally uses a simple opening book.

During midgame it searches and evaluates about 200.000 nodes per second on a PIII 750 MHz, in the endgame this number is significantly higher due to more transpositions and a less expensive evaluation function.

What's New in This Release:

  • Russian translation. (Alexandre Prokoudine)
  • Fixed problem with non-latin UTF-8 characters. (Vyacheslav Sdiconov)
  • Trippled the size of the opening book.
  • Made the hints unsensitive at startup.
  • Man page for Debian.
    Sirius 0.8.0 supports different languages (including english). It works with Linux.

    Downloading Sirius 0.8.0 will take several seconds if you use fast ADSL connection.
