[rules-users] newbie: Can rules planner provide me with the "single-steps" to the optimal binpacking solution ?

Hello, I would like to solve a 2D binpacking problem. I have an existing bin-packing solution and would like to make it more "optimized". Each change (movement of items between bins) has a certain cost, and I would like to have a list of the least-cost path. There is more than one solution that is optimal. Given an existing bin-packing solution I can tell if it is the optimal solution, and if not I can have a gross estimate to the distance to the optimal solution (although it is not guaranteed to be less than the actual distance). It sounds to me that I need something like the A-Star algorithm. Can Drools help me in solving this problem ? Thanks, Itai
