Thanks @MasterScrat for the kind reply.
May I know how much difference it may be between round 1 and round 2?
Consider the example with two different settings:
- when we just need our algorithm to work with map size 150 * 150
- when we also need our algorithm to work with map size 1500 * 1500
It may be quite different to design a optimal state/algorithm when the problem settings are different.
