  Definition of Heuristic (computer science)
Here, a heuristic is a function, h(n) defined on the nodes of a search tree, which serves as an estimate of the cost of the cheapest path from that node to the goal node.
Heuristics improve the efficiency of search algorithms by reducing the branching factor from b to (ideally) a low constant b*.
When the word heuristic is used in rule-based language processing (stemming), pattern recognition (the features are heuristics) or image processing, it is often used to refer to the rules themselves and practitioners often use the word to mean ad hoc.

In computer science, a heuristic is a technique designed to solve a problem that ignores whether the solution can be proven to be correct, but which usually produces a good solution or solves a simpler problem that contains or intersects with the solution of the more complex problem.
