optimization (ACO) and simulated annealing (SA), called (liACO) to design of
communication networks. The design problem is to find the optimal network topology where
total cost is minimum and all-terminal reliability is not less-than a given level of reliability.
The effectiveness of the liACO is investigated comparing its results with those obtained by
SA and ACO, which are basic forms of the liACO, and also GAs given in the literature for the …
