A Multiobjective Brain Storm Optimization Algorithm Based on Decomposition

Pseudocode 1

The pseudo code of the BSO algorithm.

(1) Initialization: Generate an solutions randomly or by a problem-specific method and evaluate these solutions

While the stopping criterion is not met do

Clustering: cluster solutions into clusters by a clustering algorithm;

Generating new solutions: randomly select one or two cluster(s) to produce new solutions.

Updating: compare the new solution with the existing solution with the same cluster; the better one is kept and recorded

as the new solution.
