maERO: ERO rule for minimum cost arborescence problems
Description
Given a graph with a minimum cost arborescence, the
maERO function divides the cost of the arborescence
among the agents according to the ERO rule. For that
purpose, the irreducible form of the problem is obtained.
The ERO rule is just the Shapley value of the cooperative
game associated with the irreducible form.
Usage
maERO(nodes, arcs)
Arguments
nodes
vector containing the nodes of the graph,
identified by a number that goes from $1$ to the
order of the graph.
arcs
matrix with the list of arcs of the graph.
Each row represents one arc. The first two columns
contain the two endpoints of each arc and the third
column contains their weights.
Value
maERO returns a matrix with the agents and their
costs.
