Design and Management of Complex Technical Processes and Systems by means of Computational Intelligence Methods Design and Analysis of an Asymmetric Mutation Operator

چکیده
Evolutionary algorithms as general randomized search heuristics typically perform a random search that is biased only by the fitness of the search points encountered. In practical applications the use of biased variation operators suggested by problem-specific knowledge may speed-up the search considerably. Problems defined over bit strings of finite length often have the property that good solutions have only very few one-bits or very few zero-bits. Here, one specific mutation operator that is tailored towards such situations is defined and analyzed. The assets and drawbacks of this mutation operator are discussed. This is done by presenting analytical results on illustrative example functions as well as on function classes.

Increasing of net energy storage (Q net) and discharge time of phase change material (t PCM), simultaneously, are important purpose in the design of solar systems. In the present paper, Multi-Objective (MO) based on hybrid of Particle Swarm Optimization (PSO) and multiple crossover and mutation operator is used for Pareto based optimization of solar systems. The conflicting objectives are Q net...
