The optimization of shell-and-tube heat exchangers with fourdifferent methods is studied, considering the impact of control parameter settings and problem formulation, and using a realistic equipment cost model. One formulation with mainly continuous variables, and three enforcing standard discrete dimensions are evaluated. The effect of both problem formulation and algorithm tuning was clear, underlining the need for sufficient coverage of both for meaningful optimizer performance comparisons. Tailoring the problem formulation to the characteristics of the optimizer was shown to be useful. Of the considered optimizers, differential evolution was clearly superior to others. For particle swarm and genetic algorithm, findings contradict earlier studies.
