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 .
