Marvin,
an UCI and Chess Engine Communication Protocol compatible chess engine by Martin Danielsson, written in C. Marvin was originally developed in the early 2000s until 2005, released in May 2004 [2] and January 2005 [3] as closed source engine. After ten years "out of business", Martin Danielsson restarted the development in 2015 - the completely rewritten Marvin 2.0.0 was released as open source engine under the terms of the GNU General Public License (GPL3) in March 2017 [4].
