heuristic

heuristic / heuristic / heuristic

AdjectiveNoun

pl: heuristics

This term describes a pragmatic approach to problem solving that prioritizes speed and efficiency over absolute precision. It evokes the image of a shortcut or a rule of thumb used when a perfect solution is computationally impossible or practically unattainable. In cognitive psychology, it refers to the mental shortcuts the brain uses to make quick decisions, which can lead to cognitive biases. In computer science, it describes algorithms that find a good enough solution when an exhaustive search would take too long.
