  Abstract/
Summary
In this paper, three new methods for the solution of the off-line Traffic Engineering problem in multi-service networks based on computational intelligence are presented. In the first method the off-line TE problem is formulated as an optimisation model with linear constraints and then solved using a modified version of the Genetic Algorithm for Numerical Optimisation for Constraint Problems (GENOCOP). Besides, a hybrid method for the solution of the aforementioned problem involving GENOCOP and a heuristic TE algorithm is also provided. In the third method the off-line TE optimisation problem is solved using a special constrained simulated annealing algorithm. The performance of the above methods against a standard optimisation method based on Linear Programming is examined through a series of tests and numerical results are provided.
