All known techniques for handling complex problems successfully seem to fall into one of the three classes: subdividing the problem(51), ignoring irrelevant detail in a safe way(52), and having an independent agent(53)the internal consistency(contextual checking). The first two provide guidelines for solving the problem, the third serves to provide early warnings. A good programming language supports all three.In subdividing problem, some of the subproblems may be similar to the(54) problem. It leads us to a(55)solution. This(55)solution is viable provided each of the subproblems is easier to solve than the original problem.
