RuyTune’s hyperbolic tangent based Sigmoid [1] RuyTune,
an open source framework for tuning evaluation function parameters, written by Álvaro Begué in C++, released on Bitbucket [2] as introduced in November 2016 [3]. RuyTune applies logistic regression using a limited-memory BFGS, a quasi-Newton method that approximates the Broyden–Fletcher–Goldfarb–Shanno algorithm with limited amount of memory. It uses the libLBFGS library [4] along with reverse-mode automatic differentiation and requires that the evaluation function is converted to a C++ template function where the score type is a template parameter, and a database of quiescent positions with associated results [5].
