The Cross Entropy (CE) Method: CE (Rubinstein and Kroese, 2004) is an iterative method whose goal is to optimize a function f parameterized by a vector Œ∏ ‚àà Œò by direct search in the parameter space Œò. Figure 7 contains the pseudo-code of the CE algorithm used in our experiments (Szita and LoÃãrincz, 2006; Thiery and Scherrer, 2009b).
