A multi objective self adaptive differential evolution algorithm for conceptual high rise building design
This paper presents a multi objective self adaptive differential evolution algorithm to solve the form finding problem of high rise building design in the conceptual phase. The aim of the research is to reach suitable high rise design alternatives for hard and soft objectives, which are construction cost per square meter, structural displacement, and visual perception of the spaces from the inside out subject to several constraints that are related with both high rise construction regulations, and profitability of the spaces. We formulate the problem as a multi objective realparameter constrained optimization problem for three objectives that are inherently conflicting. To tackle this problem, we developed two different optimization algorithms, namely, a Non Dominated Sorting Genetic Algorithm II (NSGA II) and a Self Adaptive Differential Evolution Algorithm (jDE) in order to obtain Pareto fronts with diversified non dominated solutions. The extensive computational results show that the jDE algorithm yields much more desirable Pareto front than the NSGA II algorithm.
