Search tree-based approach for the p-median problem using the ant colony optimization algorithm [PDF]

open access: yesComputer Science Journal of Moldova, 2014
In this paper we present an approximation algorithm for the $p$-median problem that uses the principles of ant colony optimization technique. We introduce a search tree that keeps the partial solutions during the solution process of the $p$-median ...
