Heuristic
Heuristic (originally known as heuristic approach, heuristic method, or heuristic technique; from Greek εὑρίσκω: to find, discover) is any approach, technique, and/or practice that utilizes one or more experiments to discover knowledge and/or to solve a problem.
Heuristics are often used in situations when finding an optimal solution is impossible or impractical. This discovery, solution, and/or, especially, the process of achieving an ultimate objective may or may not be optimal, perfect, or rational, but, instead, sufficient for 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.
