Heuristic
Heuristic (originally known as heuristic approach or heuristic technique; from Greek εὑρίσκω: to find or discover) is any approach, technique, and/or practice that utilizes one or more experiments to discover knowledge and/or to solve a problem. This discovery or solution may or may not be optimal, perfect, or rational, but, instead, sufficient for reaching an ultimate goal. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision.[1]:94 Examples that employ heuristics include using a rule of thumb, an educated guess, an intuitive judgment, a guesstimate, profiling, or common sense.
