A novel pre-multimodal evolutionary optimization inspec- tion of the fitness landscape for an objective function would generally be highly needed and is therefore proposed in present paper. An evolution- ary population of samples in the domain of a given problem is generated and clustered by means of two appropriately chosen approaches. The aim is to direct a set of samples towards the basins of attraction within the landscape of a function and subsequently group them around some ap- proximate optima.What results from the suggested evolutionary-clustering tool is an estimation of the number of potential solutions for the problem and consequently an informed choice for parameter setting in subpopu- lation demarcation within a multimodal technique that would tackle the considered objective.
