‘Heuristics’ refers to the random trial and error methods or the experience based techniques used for solving of problems.The heuristics method of solving problems starts with a collection of unknown factors, and then proceeds with the independent experimental exploration for each of the factors.
As against a regular defined SOP (Standard Operating Procedure) or a predetermined algorithm, which end up following a systematic procedure and reach a definite conclusion; the heuristic or trial and error procedure is exactly the opposite of the former. In heuristics, each step involves the rule of the thumb, and each step depends on the results of the previous experimentation stage, which is unknown and unpredictable too. Heuristics may or may not end up reaching a definite conclusion or delivering desired or requisite results in terms of optimum and definite deliverables.
Heuristics are widely studied and employed in various fields of study like psychology, philosophy and mental sciences. Additionally, heuristics are largely employed in various areas of business, law, marketing, research, engineering, statistics and communication.
