IProblem< T > Interface Template Reference

Description

Represents the multicriteria optimization (MCO) problem solved by the AI system(interface).

This is done by a solver, e.g. an ISolver<T>.

An IProblem<T> can be seen as a matrix, whereby a row represents an objective and a column represents associated values for each objective. So, classes implementing this interface should ensure that each objective has got the same number of values. Every IProblem<T> stores the information whether it is to be minimized or maximized so that an ISolver<T> is able to distinguish between those two operations.

Template Parameters

T	Type of the objective values defining the objective space.
