ant colony optimization

Overview page. Subjects: Computing — Probability and Statistics.

An optimization procedure that seeks to mimic an ant's apparent ability to find the shortest distance between two points. The ant's choices are based on the quantities of pheromones left by...

characteristic function

Overview page. Subjects: Probability and Statistics — Computing.

Of a subset S of a universal set U. A function that indicates whether or not an element is a member of the subset S. It is the function f: U → {0,1} defined as follows: f(x) = 1 if xSnull...

complexity

Overview page. Subjects: Computing — Probability and Statistics.

A measure of the computer time or space required to solve a problem by means of an algorithm of interest, expressed as a function of the dimensions of the problem. If a problem with n dimen...
