Heuristic

adj.

enabling someone to discover or learn something for themselves. “a “hands-on” or interactive heuristic approach to learning”

noun

a heuristic process or method.

A heuristic technique, or a heuristic (/hjʊəˈrɪstɪk/; Ancient Greek: εὑρίσκω, heurískō, ‘I find, discover’), is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. 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.
