Detailed Description

Example: Clique-based graph coloring

Definition at line 308 of file graph-color.cc.

Graph specification for graph coloring
The edges are described by an array of integers with even number of elements, terminated by the elements -1,-1. The cliques are described by an array of integers, where the first integer gives the size of the clique, the following elements are nodes for each clique. The cliques are terminated by -1 for clique size
const int	g1_e []
	First example graph: edges.
const int	g1_c []
	First example graph: cliques.
const GraphColorSpec	g1 (200, g1_e, g1_c)
	First example graph.
const int	g2_e []
	Second example graph: edges.
const int	g2_c []
	Second example graph: cliques.
const GraphColorSpec	g2 (200, g2_e, g2_c)
	Second example graph.
Public Types

Member Enumeration Documentation

anonymous enum

Model variants.

Enumerator:

MODEL_NONE	No lower bound.
MODEL_CLIQUE	Use maximal clique size as lower bound.

anonymous enum

Branching to use for model.

Enumerator:

BRANCH_DEGREE	Choose variable with largest degree.
BRANCH_SIZE	Choose variable with smallest size.
