Releases
  • IPPOLIT, released on May 2, 2009, was the first release of the series. It was split in multiple usenet messages.[3]
  • RobboLito, released in September 2009, was the second installment of the IPPOLIT series. Endgame tablebase, RobboBases support was introduced.
  • Igorrit, released in January 2010, added Multi-core support, and was the third installment of the IPPOLIT series.
  • IvanHoe, released in January 2010, is the fourth and current project code name of the IPPOLIT series. It features, but not limited to, Multi-PV, Monte-Carlo Tree Search, and Chess960. IvanHoe uses a decrementing versioning scheme. The latest release includes source-code for a Java GUI, ComradesGUI.

Controversy

IPPOLIT was initially prohibited from many computer chess websites after the author of the chess engine Rybka claimed it to be a clone of his program.[4] IPPOLIT authors have denied the accusation. Even today, some chess rating lists still refuse to include it in their lists of tested programs.

gollark: Besides, it's easy to navigate them just by scrolling right/left and having them be divided into multiple windows.
gollark: Also, I get to dazzle people with my tab count.
gollark: Unused tabs don't occupy much RAM, and I enabled the setting to keep tabs when I open and close it, so it works nicely.
gollark: Well, because I inconsistently jump around between various things, and use tabs as markers of "look at this at some point".
gollark: Big difference.
