Method Detail

getCosts

public java.util.Map<java.lang.Integer,java.lang.Double> getCosts(java.lang.Integer from,
                                                                  java.util.Set<java.lang.Integer> to)

Calculates total costs to the given set of target nodes. The cost to a node is the sum of complements of probabilities that all the links come up as the next contact of the nodes.

Parameters:

from - The index (address) of the start node

to - The address set of destination nodes

Returns:

A map of (destination node, cost) tuples
