## 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. |
