COMPARISON OF MODERN HEURISTICS ON SOLVING THE PHASE STABILITY TESTING PROBLEM

摘要

In this paper, we are concerned with the phase stability testingat constant volume, temperature, and moles (V TN-specification) of a mul-ticomponent mixture, which is an unconstrained minimization problem. Wepresent and compare the performance of five chosen optimization algorithms:Differential Evolution, Cuckoo Search, Harmony Search, CMA-ES, and Ele-phant Herding Optimization. For the comparison of the evolution strategies,we use the Wilcoxon signed-rank test. In addition, we compare the evolutionstrategies with the classical Newton-Raphson method based on the computa-tion times. Moreover, we present the expanded mirroring technique, whichmirrors the computed solution into a given simplex.
