Derivative-free and blackbox optimization pdf
WebThis paper analyzes and extends the large-scale version of the well-known cooperative coevolution (CC), a divide-and-conquer optimization framework, on non-separable functions, and formalizes it to a continuous game model via simplification, but without losing its essential property. Given the ubiquity of non-separable optimization problems in real … WebInformation geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a Riemannian manifold, defining a parametrization-invariant first order differential equation …
