WebConstrained optimization problems (COPs) are widely encountered in chemical engineering processes, and are normally defined by complex objective functions with a large number of constraints. Classical optimization methods often fail to solve such problems. In this paper, to solve COPs efficiently, a two-phase search method based on a heat transfer search … WebIn this paper we explore the advantages of using Self-Organized Maps (SOM) when analyzing geodemographic data. The standard SOM algorithm is presented, together with a few variants. The strengths and weaknesses of those different variants are shown, and their use in this type of problems is discussed.
