CLOP for Noisy Black-Box Parameter Optimization, a program used for parameter tuning, created by Rémi Coulom. The CLOP principle, which stands for Confident Local OPtimization, is an approach to local regression that overcomes problems with very noisy outputs and nonnegative Hessians in a simple and efficient way. CLOP is suited to tune several parameters simultaneously, and requires polynomial time for each additional parameter to verify the tuned values, that is playing a lot of games.
