Class ImmutableProblem

java.lang.Object

de.stups.probkodkod.ImmutableProblem

public final class ImmutableProblem
extends java.lang.Object

This is the immutable Version of a Kodkod problem description. Objects of this class are usually stored in the KodkodSession. Aside the universe, the relations and the formula, this class contains the default bounds for the relations. It distinguishes between exact bounds (constants) and upper bounds (variables). In a request (see #createRequest(Solver, Map)), values for variables can be given and the computed values of the remaining variables are returned. This way, no redundant constants are passed between client and server.
