Abstract
U radu je opisan problem rukovanja ograničenjima prostora u diferencijalnoj evoluciji (DE), evolucijskom algoritmu koji se često koristi za optimizacijske probleme. Prikazana su četiri različita mehanizma za rukovanje ograničenjima prostora: projekcija, refleksija, ponovna inicijalizacija te konzervativna metoda. Dan je pregled osnovnih koraka DE i razlog zbog kojeg rješenja uopće izlaze iz granica prostora. Implementirana je standardna inačica algoritma DE i dan je opis i prikaz načina rada. Ostvareno programsko rješenje omogućuje izvođenje algoritma DE s prilagodljivim parametrima i odabirom različitih funkcija cilja. Odrađena je analiza učinkovitosti sva četiri mehanizma na nekoliko poznatih optimizacijskih problema. Kroz rezultate analize, pokazano je da odabir mehanizma za rukovanje ograničenjima, kao i odabir parametara algoritma, može znatno utjecati na učinkovitost algoritma.
Abstract (english)
The paper addresses the problem of handling bound constraints in Differential Evolution (DE), an evolutionary algorithm frequently used for optimization problems. Four different mechanisms for handling bound constraints are presented: projection, reflection, reinitialization, and the conservative method. An overview of the basic steps in DE is given, along with an explanation of why solutions can be out of bounds. A standard version of the DE algorithm has been implemented, and its use was demonstrated. The developed software solution allows for the execution of the DE algorithm with adjustable parameters and the choice of different objective functions. An analysis of the efficiency of all four constraint-handling mechanisms has been conducted on several wellknown optimization problems. The results demonstrate that the choice of constraint-handling mechanism, as well as the selection of algorithm parameters, can significantly impact the algorithm's efficiency.
