Heuristic vs Algorithm: What’s the Difference?
The difference at a glance
An algorithm is a precise, step-by-step procedure guaranteed to produce a correct result — it is exact, exhaustive, and systematic. A heuristic is a practical shortcut: faster and simpler than an algorithm, good enough for most situations, but not guaranteed. Algorithms eliminate uncertainty; heuristics manage it. In a world where we can't compute everything from first principles, heuristics are what make us functional — at the cost of occasional error.
