Problem< T > Class Template Reference

Description

Represents the multicriteria optimization (MCO) problem solved by the AI system (implementation as base class).

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

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

Template Parameters

T	Type of the objective values defining the objective space.
