In optimization (a branch of mathematics) and search algorithms (a topic in computer science), a candidate solution is a member of a set of possible solutions to a given problem. A candidate solution does not have to be a likely or reasonable solution to the problem – it is simply in the set that satisfies all constraints.
The space of all candidate solutions is called the feasible region, feasible set, search space, or solution space.
In the case of the genetic algorithm, the candidate solutions are the individuals in the population being evolved by the algorithm.
Famous quotes containing the words candidate and/or solution:
“A candidate once called his opponent “a willful, obstinate, unsavory, obnoxious, pusillanimous, pestilential, pernicious, and perversable liar” without pausing for breath, and even his enemies removed their hats.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
“What is history? Its beginning is that of the centuries of systematic work devoted to the solution of the enigma of death, so that death itself may eventually be overcome. That is why people write symphonies, and why they discover mathematical infinity and electromagnetic waves.”
—Boris Pasternak (1890–1960)
