From The Collaborative International Dictionary of English v.0.48 :

  Heuristic \Heu*ris"tic\ (h[-u]*r[i^]s"t[i^]k), a. [Gr.
     e"yri`skein to discover.]
     1. Serving to promote discovery or learning; -- used
        especially of thories or paradigms which stimulate new
        ideas for discovering facts in experimental sciences.
        [1913 Webster +PJC]
     2. Serving to stimulate people to learn and discover on their
        own, especially by encouraging experimental and
        trial-and-error methods for solving problems.
     3. Pertaining to or based on trial-and-error and experimental
        methods of learning and evaluation.
     4. (Computers) Based on the use of an efficient trial-and
        error method to search a space of possible solutions to a
        problem, or to find an acceptable approximate solution,
        when an exact algorithmic method is unavailable or too

From The Free On-line Dictionary of Computing (30 December 2018) :

  non-algorithmic procedure
     1.  A rule of thumb, simplification, or educated
     guess that reduces or limits the search for solutions in
     domains that are difficult and poorly understood.  Unlike
     algorithms, heuristics do not guarantee optimal, or even
     feasible, solutions and are often used with no theoretical
     2.  approximation algorithm.
