Solving constrained mirror placement problem is very valuable to content providers in Internet.Constrained mirror placement problem can be modeled as a
k
-supplier problem
which belongs to NP-Complete problem and has only best possible 3-approximate algorithm.A heuristic genetic algorithm is presented in this paper
which uses the heuristic algorithm to revise the new illegal chromosome generated by standard two-points crossover and one-point mutation operations.The simulation results suggest that the algorithm is feasible and effective.
