Method Detail

probability

public double probability(Topology.City from,
                          Topology.City to)

Description copied from interface: TaskDistribution

Returns the probability that a task to to is available in city from. If to is null then the probability that there is no task available in city from is returned.

Specified by:

probability in interface TaskDistribution

Parameters:

from - the source of the task

to - the destination of the task, or null

reward

public int reward(Topology.City from,
                  Topology.City to)

Description copied from interface: TaskDistribution

Returns the (expected) reward for a task between two cities.

Specified by:

reward in interface TaskDistribution

Parameters:

from - the source of the task

to - the destination of the task

weight

public int weight(Topology.City from,
                  Topology.City to)

Description copied from interface: TaskDistribution

Returns the (expected) weight for a task between two cities.

Specified by:

weight in interface TaskDistribution

Parameters:

from - the source of the task

to - the destination of the task

createTask

public Task createTask(Topology.City from)

createTaskSet

public TaskSet createTaskSet(int size)

createTaskSet

public TaskSet createTaskSet(Task[] tasks)
