Abstract
U radu su razmotrene dvije inačice algoritma diferencijalne evolucije, jednog od najpopularnijih evolucijskih algoritama koji se pokazao vrlo učinkovit za probleme kontinuirane optimizacije. Inačice se razlikuju samo u načinu obnavljanja populacije, jedna sa sinkronim gdje se populacija obnavlja generaciju po generaciju, a druga sa asinkronim gdje se populacija obnavlja odmah kada su nova kvalitetnija rješenja dostupna. Upotrebom ostvarenog programskog rješenja provedena je eksperimentalna analiza u kojoj su dvije inačice algoritma primijenjene na deset često korištenih testnih funkcija pri dvije različite dimenzionalnosti. Također je razmotren utjecaj parametra veličine populacije korištenjem tri različite vrijednosti istog. Ostvareni rezultati daju uvid u to kako način obnavljanja populacije direktno utječe na performanse algoritma. Daljnjom usporedbom dvije inačice primijećeno je da ona sa asinkronom implementacijom obnavljanja populacije ostvaruje bolje performanse u usporedbi sa standardnom, sinkronom inačicom u većini slučajeva.
Abstract (english)
The thesis discusses two implementations of the differential evolution algorithm, one of the most popular evolutionary algorithms, which has proven to be highly effective in problems of continuous optimization. The implementations differ only in the method of population updating: one using a synchronous method, where the population is updated generation by generation, and the other using an asynchronous method, where the population is updated immediately when new, better solutions become available. Using the implemented software solution, an experimental analysis was conducted in which the two implementations of the algorithm were applied to ten commonly used benchmark functions at two different dimensionalities. The impact of the population size parameter was also examined by using three different values of it. The obtained results provide insight into how the method of population updating directly affects the algorithm's performance. Further comparison of the two variants revealed that the asynchronous implementation achieves better performance compared to the standard synchronous implementations in most cases.
