Free Essays on Heuristic Problem Solving

Heuristic problem solving – are common-sense rules drawn from experience, used to solve problems. Or simply put the heuristic method of problem solving is a rule of thumb. By contrast, algorithms are straightforward procedures that are guaranteed to work every time. Heuristic programming characterizes programs that are self-learning; they are a part of artificial intelligence, they get better with experience. Heuristic programs do not always reach the very best result but usually produce good results within a reasonable amount of search time. As discussed in the April 1998 Phi Delta Kappa article titled â€Å"What is problem solving†, general heuristics are â€Å"cognitive rules of thumb that are useful in solving a great variety of problems†. Specific heuristics are used in specialized areas, often-specific subject domains or professions. There are three common methods in heuristic problem solving. First, the most powerful general heuristic is to form a sub-goal to reduce the discrepancy between your present state and your ultimate goal state. Do something to get a little closer to the end goal. Problems defy one-shot solutions; they must be broken down into smaller parts. A second heuristic method seeks to solve problems by "working backward." First, consider your ultimate goal. From there, decide what would constitute a reasonable step just prior to reaching that goal. Then ask yourself, what would be the step just prior to that? Beginning with the end, you build a strategic bridge backward and event ually reach the initial conditions of the problem. The third heuristic method seeks to solve problems through "successive approximation." Initial tries at solving a problem may result in a product that is less than satisfying. Writing is a good example. Few accomplished writers attempt to write perfect prose the first time. Rather, the initial goal is a rough draft or an outline or a list of ideas. Over time, a manuscript is ...
