Abstract

The elephant herding optimization (EHO), which imitates social behaviors of the elephants, is recently proposed a swarm
intelligence and population-based optimization algorithm. Although EHO is a good at local search, it is not effective on the
global search due to the rapid loss of population diversity. In the basic EHO method, a single solution search equation is used
for the generating the new individuals. Therefore, it is insufficient on the solving the problems which have different
characteristics and the exploring the search space effectively. In this study, in order to overcome these problems and to provide
a balance between exploration and exploitation, elephant herding optimization using multi-search strategy (Multi-EHO) has been
proposed which inspired by the search strategies of the most well-known optimization techniques. For the comparison of the
proposed method and the basic EHO, the CEC2015 benchmark set with 15 different functions is used. In addition, to validate
the performance of Multi-EHO, the proposed method is compared with the grey wolf optimizer (GWO) and the whale
optimization algorithm (WOA) proposed in recent years. Experimental results show that the proposed method has more
successful and more robust performance than other methods.-

Sürekli Optimizasyon Problemleri için Çoklu Arama Stratejisi Kullanan Fil Sürü Optimizasyonu

Abstract

Fillerin sosyal davranışlarını taklit eden fil sürü optimizasyonu (EHO), yakın zamanda önerilen sürü zekası ve popülasyon tabanlı
bir optimizasyon algoritmasıdır. EHO, yerel arama konusunda iyi bir yeteneğe sahip olmasına rağmen popülasyon çeşitliliğini
erken kaybetmesi nedeniyle global aramada etkili olamamaktadır. Temel EHO yönteminde, yeni bireylerin oluşturulması için
tek bir çözüm arama denklemi kullanılmaktadır. Bu nedenle, arama uzayının etkili bir şekilde araştırılmasında ve farklı
karakteristikteki problemlerin çözümünde yetersiz kalmaktadır. Bu çalışmada, bu sorunların üstesinden gelmek ve keşif ve
faydalanma arasındaki dengeyi sağlayabilmek için en çok bilinen optimizasyon tekniklerinin arama stratejilerinden esinlenilerek
çoklu arama stratejisi kullanan fil sürü optimizasyonu (Multi-EHO) önerilmiştir. Önerilen yöntem ile temel EHO‘nun
karşılaştırılması için farklı karakteristikteki 15 fonksiyona sahip CEC2015 test seti kullanılmıştır. Ayrıca Multi-EHO’nun
performansını doğrulamak için, önerilen yöntem son yıllarda önerilen gri kurt algoritması (GWO) ve balina optimizasyonu
algoritması (WOA) ile karşılaştırılmıştır. Deneysel sonuçlar, önerilen yöntemin diğer yöntemlere göre daha başarılı ve daha
sağlam bir performansa sahip olduğunu göstermektedir.
