Eastern spiny mouse - a Rodent [1]

Rodent,
an UCI compliant open source chess engine by Pawel Koziol licensed under the GPL, initially based on Sungorus 1.4 by Pablo Vazquez, with evaluation parameters borrowed from the Toga log user manual. Rodent may be regarded as a beefed up bitboard version of the CPW-Engine [2], and features adjustable playing strength and different personalities. Rodent II, released in February 2016 [3], was a complete rewrite, now using the magic bitboard implementation by Pradu Kannan. Rodent III, released in March 2017, has been programmed for tunability. One can turn it into a crazy attacker or an old-fashioned positional player [4].
