| Outline of Final Research Achievements |
In this work, we have studied the Information-Geometric Optimization (IGO) that is a recently proposed framework of probability model based search algorithm for arbitrary optimization problems based on the information geometry. We have designed a novel variant of the covariance matrix adaptation evolution strategy for high dimensional continuous optimization, a new algorithm for constraint continuous optimization, both of which are based on the IGO principle. We have also studied the runtime of a general comparison based algorithm with fitness averaging strategy on noisy discrete optimization problems and derived the required number of fitness resampling.
