Ant based optimisation methods were invented by Marco Dorigo and so far have been used almost entirely for order-based problems (finding routes in communication nets or manufacturing scheduling task orderings), the basic ant methods are not apparently suitable for searching in Real-valued spaces or in combinatorial but non-ordered spaces. The aim is to look into various ways of extending the an...

The timetabling of lecturers, seminars, practical sessions and examinations is a core business process for academic institutions. A feasible timetable must satisfy hard constraints, an optimum timetable will additionally satisfy soft constraints, which are not absolutely essential. An Ant Colony based Timetabling Tool (ANCOTT) has been developed for solving timetabling problems. New variants of...

Image enhancement improves the visual looks of the images . In this paper various algorithm which are used to enhance the quality of the image are surveyed ,special attention is given to L0 norm and ant colony based optimisation algorithms.

In this paper we present an Ant Colony Optimisation based algorithm to determine the Pareto set for the Multiple Objective Travelling Salesman Problem. Our results are then compared with the ones obtained with a genetic algorithm.
