The problem of heuristic programming-of making computers solve really difficult problems- are divided into five main areas. Search, pattern recognition, Learning, Planning, and Induction. Whenever appropriate, the discussion is supported by extensive citation of the literature and by descriptions of a few of the most successful heuristic (Problem-solving) programs constructed to date.

The adjective "heuristic," as used here and widely in the literature, means related to improving problem-solving performance; as a noun it is also used in regard to any method or trick used to improve the efficiency of a problem-solving system. A "heuristic program," to be considered successful, must work well on a variety of problems, and may often be executed if it fails on some. We often find it worthwhile to introduce a heuristic method, which happens to cause occasional failures, if there is an overall improvement in performance. But imperfect methods are not necessarily heuristic, nor vice versa. Hence “heuristic” should not be regarded as opposite to “foolproof”; this has caused some confusion in the literature.

What is heuristic programming?
