Method Detail

getInitState

public static PackageState getInitState(long seed,
                                        java.util.List<Agent> agts,
                                        int numPackages,
                                        int numDests,
                                        int mapSize)

Use the given seed to generate a pseudo-random initial state for the vacuum world.

getInitState

public static PackageState getInitState(java.util.List<Agent> agts,
                                        int numPackages,
                                        int numDests,
                                        int mapSize)

Return a random initial state for the vacuum world.
