A Simplified Group Search Optimization Algorithm Using Improved Sharing Strategies
Gao Shou-ping · Computer Engineering and Science · 2011
This paper presents an improved GSO algorithm.The modification has three main aspects: firstly,uses an improved sharing strategy which shares not only the best member but also the other good members' information;secondly,uses completely random search instead of search by the head angle;thirdly,restricts the number of changing dimensions of the scroungers.Among them,the first one is proposed in this paper.When tested against six benchmark functions,in low and high dimensions,the improved algorithm has a competitive performance to GSO,GA and PSO,especially on high-dimensional problems.
