Multimodal Deceptive Functions

This pap er presents a static analysis of deception in multimodal funct ions. Deception in a bipolar function of unitation (a function with two global optima and a number of decepti ve attractors) is defined, and a set of suffic ient conditions relat ing function values is obtained. A bipolar decept ive function is also constructed from low-order Walsh coeffic ients. Multimodal functions of bou...
