Abstract The number of solutions obtained is too large to provide a set with good performance in the nearby area true Pareto front when problem-specific preferences are unavailable. Therefore, this paper proposes knee point-driven many-objective pigeon-inspired optimization algorithm (KnMAPIO). An environmental selection strategy based on knee-oriented dominance proposed improve pressure and po...

the synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. to provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
