What's the difference between algorithm and heuristic?

Algorithm


Definition:

  • (19) Our results show that although kriging is a statistically optimal method, it is not markedly better than simpler interpolation algorithms, though it is considerably more complex to use.
  • (20) The algorithm is an improvement over the sphere model in that it considers two distinct surfaces: an ellipsoid, to model the region of the skull on which the sensors are placed, and a sphere as the medium in which the current dipole model is considered.

Heuristic


Definition:

  • (a.) Serving to discover or find out.

Example Sentences:

  • (1) Two methods for diagnostic classification of the electrocardiogram are described: a heuristic one and a statistical one.
  • (2) Within the Theory of Dual Radiation Action, the heuristically useful function, gamma(chi), that two energy depositions, a distance chi apart, will result in observable damage can be written in terms of two more fundamental quantities: One, s(chi), describes the structure of the sensitive matrix of the cell.
  • (3) The immune alterations of Down's syndrome and those of infantile AIDS may be taken as heuristic examples in this sense.

  • (10) (i) knowledge about the processes of the system under investigation, expressed in terms of a Continuous System Simulation Language (CSSL); (ii) heuristic knowledge on how to reach the goals of the simulation experiment, expressed in terms of a Rule Description Language (RDL); and (iii) knowledge about the requirements of the intended users, expressed in terms of a User Interface Description Language (UIDL).
  • (11) In Duchenne muscular dystrophy the course of the different enzyme activities can be described by an heuristic mathematical formula (y = Ae-at + bte-ct).
  • (12) The starting points for energy minimizations were generated from the following two types of inputs: (a) the amino acid sequence and (b) the heuristic inputs, which were derived according to physical, chemical, and biological principles by piecing together all useful information available.
  • (13) Thirdly, neuropsychological-neurophysiological studies are "heuristic" fishing-expeditions to find a presumed abnormality to account for psychopathology, without doing the prospective longitudinal research necessary to validate such theory.
  • (14) Superficial knowledge level characterized by the intuitive reasoning from test results to diseases and deep knowledge level referring to the relations among the pathophysiologic states were stratified, and the heuristics based on the experiences at bed-side were incorporated in this knowledge representation.
