Improved RWCE Algorithm with Integer/Continuous Variable Separation Optimization Strategy to Protect Efficient Structure

doi:10.19596/j.cnki.1001-246x.8188

Abstract

Abstract: As random walk algorithm with compulsive evolution is used to optimize heat exchange network, the structure with lower annual cost in continuous variable evolution stage is destroyed by integer variable evolution operation. As a result, the structure formed after the evolution of continuous variables can not play its full advantages, which restricts the evolution of continuous variables. We propose an optimization strategy of separating continuous variables and integers to protect the effective structure, thereby, protecting structures with development potential and reducing the combined annual cost further. In example study our result is better than that in literature. Precision of the algorithm is improved, and validity of the strategy is verified.

Key words: heat exchange network, random walk algorithm with compulsive evolution, separation optimization strategy
