# Heuristical vs. Heuristic: What's the Difference?

## Heuristical and Heuristic Definitions

#### Heuristical

Of or pertaining to heuristics.

#### Heuristic

Of or relating to a usually speculative formulation serving as a guide in the investigation or solution of a problem
"The historian discovers the past by the judicious use of such a heuristic device as the 'ideal type'" (Karl J. Weintraub).

#### Heuristic

Of or constituting an educational method in which learning takes place through discoveries that result from investigations made by the student.

#### Heuristic

(Computers) Relating to or using a problem-solving technique in which the most appropriate solution of several found by alternative methods is selected at successive stages of a program for use in the next step of the program.

#### Heuristic

A heuristic method or process.

#### Heuristic

Heuristics (used with a sing. verb) The study and application of heuristic methods and processes.

#### Heuristic

(of an approach to problem solving, learning, or discovery) That employs a practical method not guaranteed to be optimal or perfect; not following or derived from any theory.

#### Heuristic

That provides a useful, but not optimal, solution to a problem. Such algorithms are typically employed either because the only known algorithms that provide optimal solutions use too much time or resources, or else because there is no known algorithm that provides an optimal solution.

#### Heuristic

(of an argument) That reasons from the value of a method or principle that has been shown by experimental investigation to be a useful aid in learning, discovery and problem-solving.

#### Heuristic

A heuristic method.

#### Heuristic

The art of applying heuristic methods.

#### Heuristic

(computing) A heuristic algorithm or method.

#### Heuristic

Serving to promote discovery or learning; - used especially of thories or paradigms which stimulate new ideas for discovering facts in experimental sciences.

#### Heuristic

Serving to stimulate people to learn and discover on their own, especially by encouraging experimental and trial-and-error methods for solving problems.

#### Heuristic

Pertaining to or based on trial-and-error and experimental methods of learning and evaluation.

#### Heuristic

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 time-consuming.

#### Heuristic

A heuristic method; a specific heuristic procedure.

#### Heuristic

A theory or approach which serves to promote discovery or learning by encouraging experimentation.

#### Heuristic

A commonsense rule (or set of rules) intended to increase the probability of solving some problem

#### Heuristic

Of or relating to or using a general formulation that serves to guide investigation
