heuristic
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.
Meanings
Relating to a process of discovery or problem solving that employs a practical method not guaranteed to be optimal, but sufficient for immediate goals.
"The team used a heuristic approach to quickly narrow down the possible causes of the system failure."
