20.500.12556/DKUM-52639 Študija samoprilagajanja krmilnih parametrov pri algoritmu DEMOwSA A study in self-adaptation of control parameters in the DEMOwSA algorithm V članku predstavljamo študijo samoprilagodljivih krmilnih parametrov algoritma diferencialne evolucije za večkriterijsko optimizacijo, ki ga krmili samoprilagoditveni mehanizem, predstavljen v evolucijskih strategijah. Samoprilagajanje parametrov omogoča danemu evolucijskemu algoritmu učinkovitejše iskanje, saj se algoritem lahko prilagodi optimizacijskemu problemu, ki ga rešuje. Z eksperimentom prikažemo dejanske vrednosti in spreminjanje samoprilagodljivih krmilnih parametrov na znanih testnih funkcijah. In this paper we present an experimental analysis showing that the self-adaptation of control parameters plays an important role in the multiobjective optimization process (refer to Figure I for notion of multiobjective optimality). Experimental results of a self-adaptive differential evolution algorithm are evaluated on the set of benchmark functions provided for the CEC 2007 Special session on Performance Assessment & Competition on Multi-objective Optimization Algorithms, as seen in Tables 2-7. Self-adaptation is proven to statistically outperform fixed parameters, using t-test on the empirical results in these tables. The values of control parameters are encoded in each individual (see Figure 2) and changed during the optimization process. They depend on the nature of the problem being solved, as can be seen in Table I and Figures 3 and 4 which show how using self-adaptation good control parameters are obtained to improve the search results. evolucijsko računanje diferencialna evolucija večkriterijska optimizacija samoprilagoditev algoritmi evolutionary computation differential evolution multi-objective optimization self-adaptation true false false Elektrotehniška zveza Slovenije Slovenski jezik Angleški jezik Delo ni kategorizirano 2015-07-10 18:02:14 2015-07-10 18:02:14 2022-06-01 03:06:58 2019-07-11 07:50:03 2008 0 0 str. 223-228 št. 4 Letn. 75 2008 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.89.021 742916 12933654 0013-5852 URN:SI:UM:DK:4MHZJHBV http://www.dlib.si/details/URN:NBN:SI:DOC-85JJUCSM 1 https://dk.um.si/Dokument.php?lang=slv&id=77198 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
