Giraffe,
an experimental open source chess engine by Matthew Lai under the GNU General Public License, compliant to the Chess Engine Communication Protocol, written in C++11 and based on deep learning, which is topic of Matthew's master's thesis in August 2015 [2] [3] . Giraffe uses the Eigen linear algebra library [4] , and Pradyumna Kannan's magic move generator [5] [6]. As employee of Google DeepMind, Matthew Lai announced the discontinuation of the Giraffe project in January 2016 [7].

Description
Giraffe's evaluation function is a deep neural network trained by TDLeaf [8] . Its feature representation includes a map of static exchange evaluations for all squares and sides [9] , a structure already proposed by Russell M. Church and Kenneth W. Church in Plans, Goals, and Search Strategies for the Selection of a Move in Chess [10] . Probability-based evaluation scores are not in centipawns nor linear to material , and span a +-10,000 range, with mate scores of +- 30,000. The search recently changed from traditional depth-based iterative deepening to assigning number of nodes (or time) to child nodes [11] . Node budget allocation will also become neural network based.
