Heuristics | ||
---|---|---|
Heuristics (from the Greek word meaning to discover) are any approach to a problem solving or self-discovery that uses shortcuts to produce good-enough solutions given in a limited time frame or deadline. In other words, it employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. We can say that heuristics are a flexibility technique for quick decisions, particularly when working with complex data.
Heuristics can be mental shortcuts that ease the cognitive load of making a decision. In simpler words, heuristics are conclusions we addopt from previous experiences we had with similar problems. We can use this approach of problem solving in human beings, machines and abstract issues. We usually use it if: ▲ we are having difficulty understanding a problem, we try drawing a picture. ▲ we can't find a solution, we try assuming that we have a solution and seeing what we can derive from that ("working backward"). ▲ the problem is abstract, we try examining a concrete example. ▲ we try solving a more general problem first (the "inventor's paradox": the more ambitious plan may have more chances of success).
