Abstract:

The algorithm simulates the movement of fish shoal in the space. According to the Euclidean distance, the neighborhood of the fish individual is divided into attraction zone, repulsion zone, and neutral zone. Furthermore, the movement trend to the food source is considered. The neighborhood factors were determined by means of the experiments. The experiments were carried out on the benchmark functions for comparison of the Novel Fish-shoal Algorithm with the Artificial Fish-swarm Algorithm. The search step size was studied experimentally. Finally a linear change weight factor strategy was proposed and the experimental results with 13 test functions verified that the proposed strategy can further improve the performance of the algorithm.

Key words: novel fish shoal algorithm, space sensing zone, optimization of swarm intelligence
