Technical Definition

Practical rules of thumb that produce good-enough solutions when optimal ones are too expensive.

How it works

From A* search heuristics to LLM prompting tricks ('think step by step'), heuristics power systems where exact methods don't scale. They are valuable but fallible — the art is knowing when a heuristic is reliable and when it isn't.
