New approach to solving the clustered shortest-path tree problem based on reducing the search space of evolutionary algorithm

作者:

Highlights:

• Suggest a method for reducing the search space of the evolutionary algorithm (EA) applied to Clustered Shortest-Path Tree Problem (CluSTP) by decomposing the original problem into two sub-problems.

• The solution of the whole CluSTP is represented compactly only by the solution of first sub-problem.

• Propose an EA to solve the first sub-problem and suggests using the exact algorithm to solve the second sub-problem.

• The Experimental results prove that the new method is more efficient than existing methods.
