An Ant System Algorithm For Graph Bisection
نویسندگان
چکیده
This paper gives an algorithm for the graph bisection problem using the Ant System (AS) technique. The ant algorithm given in this paper differs from the usual ant algorithms in that the individual ant in the system does not construct a solution to the problem nor a component of the solution directly. Rather the collective behavior of the two species of ants in the system induces a solution to the problem. The algorithm also incorporates local optimization algorithms to speed up the convergence rate and to improve the quality of the solutions. The results achieved by this algorithm on several classes of graphs equal the best known results for the majority of graphs tested, and are very close to the best known results for the remainder.

An Ant Colony Optimization Algorithm for Network Vulnerability Analysis
Intruders often combine exploits against multiple vulnerabilities in order to break into the system. Each attack scenario is a sequence of exploits launched by an intruder that leads to an undesirable state such as access to a database, service disruption, etc. The collection of possible attack scenarios in a computer network can be represented by a directed graph, called network attack gra...
متن کاملAnt Colony Algorithm for the Single Loop Routing Problem
In this paper, a new algorithm for solving the single loop routing problem is presented. The purpose of the single loop routing problem(SLRP) is to find the shortest loop for an automated guided vehicle covering at least one edge of each department of a block layout. First it shown that this problem can be represented as a graph model. Then a meta-heuristic algorithm based on and colony system ...

متن کاملMultilevel Optimization of Graph Bisection with Pheromones
We present a multiple ant-colony algorithm (MACA) for the graph bisection problem. The aim of this paper is to compare the performance of the MACA with results on the benchmark graphs from Graph partitioning Archive at the University of Greenwich. Experimental results show that the MACA is comparable with the state-of-the-art graph bisection algorithms.

The self–organizing properties of ant colonies are employed to tackle the classical combinatorial optimization problem of graph partitioning. Structural information from the graph is mapped onto an environment upon which a number of colonies compete for resources. Using Genetic Programming, a Foraging Strategy is evolved which when executed by the ants in each colony leads to a restructuring of...
