Q

Backtracking

A

“An algorithm for finding a complete solution. This is a refined brute force methodology. It is a very general algorithm for finding all (or some) solutions to computational problems. It incrementally builds to the solution, and abandons each partial success (“backtracks”) as soon as it determines that the partial solution cannot possible be completed to a valid solution.”
