A Species Conservation-Based Particle Swarm Optimization with Local Search for Dynamic Optimization Problems

Algorithm 2

The procedure of species conservation.
Input: species seed set saved at the species seed determination procedure and the newly generated population , species radius .
Output: the population after the species conservation procedure.
