Concerning the distribution of random number which is used in mutation of evolutionary pro-ramming (EP), it is desirable that the variance of the distribution should be large in first stage of evolution and should be small in mid to final stage of evolution applying on optimization problems. In order to realize such distribution of random number, we propose EEP with multi switching of parameter value of the distribution from initial value to next value at some arbitrary generation so as to decrease the variance of the distribution. Experimental results show that these switching EEP can improve convergence performance of EEP and switching effect can be recognized.
- Performance of a genetic algorithm for the graph partitioning problem, K Kohmoto, K Katayama, H Narihisa, MATHEMATICAL AND COMPUTER MODELLING, MATHEMATICAL AND COMPUTER MODELLING, 38(11-13), 1325 - 1332, Dec. 2003 , RefereedSummary:The performance of the genetic algorithm (GA) for the graph partitioning problem (GPP) is investigated by comparison with standard heuristics on well-known benchmark graphs. In general, there is a case where a practical performance of a conventional genetic approach, which performs only simple operations without a local search strategy, is not sufficient. However, it is known that a combination of GA and local search can produce better solutions. From this practice, we incorporate a simple local search algorithm into the GA. In particular, the search ability of the GA is compared with standard heuristics such as multistart local search and simulated annealing, which use the same neighborhood structure of the simple local search, for solving the GPP. Experimental results show that the GA performs better than its competitors. (C) 2003 Elsevier Ltd. All rights reserved.
- Evolutionary programming using exponential mutation, K Kohmoto, H Narihisa, K Katayama, 6TH WORLD MULTICONFERENCE ON SYSTEMICS, CYBERNETICS AND INFORMATICS, VOL XI, PROCEEDINGS, 6TH WORLD MULTICONFERENCE ON SYSTEMICS, CYBERNETICS AND INFORMATICS, VOL XI, PROCEEDINGS, vol. XI, Computer Science Ⅱ, pp. 405-410, 405 - 410, 2002 , RefereedSummary:In this paper, we present an efficient evolutionary programming with the mutation operator based on double exponential probability distribution concerning the mutation operator of evolutionary programming. There have been proposed various mutation operators by many researchers. However, the mutation operator is mainly based on normal probability distribution or Cauchy probability distribution to evolve solution for given optimization problems. The double exponential probability distribution with one positive real valued parameter has some positive amount variance and is symmetric with respect to origin. Although the variance of this probability distribution is neither infinite as Cauchy distribution, nor unit as standardized normal distribution, the amount of this variance is controllable by the value of this parameter. This fact plays an important role at the evolution process in evolutionary programming. The results of computational experiment show that our proposed evolutionary programming with double exponential probability distribution performs much better than the conventional evolutional programming when applied to the optimization problems which are well known as the benchmark problems in this research field.
