Abstract

Optimizasyon probleminde amaç sayısı arttıkça amaç uzayı da büyümektedir, bu nedenle bu problemlere cevap almak için geleneksel yöntemleri kullanmak mümkün değildir. Bu nedenle, bu sorunu çözmek için bazı yöntemler önerilmektedir. Çözümlerden birine ayrıştırma denir. Ayrıştırmada hedefler skalarizasyon fonksiyonlarına uygulanır ve birçok alt problem elde edilir. Komşuluklarına bağlı olarak, evrimsel algoritmanın mevcut neslindeki en iyi üyeler, bir sonraki nesile aktarılacaktır. Bu fikri kullanan algoritmaya Ayrıştırmaya Dayalı Çok Amaçlı Evrimsel Algoritma (MOEA/D) denir. MOEA/D algoritması ile farklı türde ayrıştırma yöntemleri kullanılabilir. Bununla birlikte, her birinin kendi zayıflıkları veya avantajları vardır. Bu nedenle, ayrıştırma yöntemlerinin dezavantajını azaltmak için bu araştırmada tek bir ayrıştırma yöntemi yerine rastgele iki yöntemin kullanılacağı hibrit bir yaklaşım önerilmiştir. Önerilen hibrit yöntemin performansı, iki metrik kullanılarak yedi test problemi üzerinde gösterilecektir.

Randomized Decomposition Methods in Multi-objective Evolutionary Algorithm based on Decomposition for Many-objective Optimization Problems

Abstract

As the number of objectives are increased in the optimization problem, the objective space is increased therefore it is not possible to use conventional methods to get answers for these problems. Therefore, some methods are proposed to solve this problem. As one of the solutions is called the decomposition. In decomposition the objectives are applied to the scalarization functions, and many sub-problems are obtained. Based on their neighborhood, the best members in the current generation of the evolutionary algorithm will be survived to the next generation. The algorithm which uses that idea is called Multi-objective Evolutionary Algorithm based on Decomposition (MOEA/D). Different typed of decomposition methods can be used with the MOEA/D algorithm. However, each of them has their own weaknesses or advantages. Therefore, to reduce the disadvantage of the decomposition methods, a hybrid approach is proposed in this research such that instead of a single decomposition method, two methods will be use randomly. The performance of the proposed hybrid method will be demonstrated on seven benchmark problems by using two metrics.
