Query: An Improved ACS Algorithm for the Solutions of Larger TSP Problems   Solving large traveling salesman problem (TSP) in an efficient way is a
challenging area for the researchers of computer science. This paper presents a
modified version of the ant colony system (ACS) algorithm called Red-Black Ant
Colony System (RB-ACS) for the solutions of TSP which is the most prominent
member of the combinatorial optimization problem. RB-ACS uses the concept of
ant colony system together with the parallel search of genetic algorithm for
obtaining the optimal solutions quickly. In this paper, it is shown that the
proposed RB-ACS algorithm yields significantly better performance than the
existing best-known algorithms.
