Computing Partial Solutions to Difficult AI Problems
Is finding just a part of a solution easier than finding the full solution? For NP-Complete problems (which represent some of the hardest problems for AI to solve) it has been shown that finding a fraction of the bits in a satisfying assignment is as hard as finding the full solution. In this paper we look at a possibility of both computing and representing partial solutions to NP-complete prob...
