Island model GP with immigrants aging and depth-dependent crossover
M. Washita, Hitoshi Iba · 2003
This paper proposes a new method for island model GP. The proposed method applies a traditional genetic operator to an aborigine and a depth-dependent crossover to the immigrants according to their ages, which show how long they survive in the island. This method can provide both local and global search strategies. The experimental results have shown that our approach works effectively.
