Method Detail

getEdgeWeight

public double getEdgeWeight(Edge edge)

Description copied from interface: WeightCalculator

Gets the weight of the given edge according to this calculator. A high weight corresponds to an edge which should not be removed for the minimal feedback arc set.

Specified by:

getEdgeWeight in interface WeightCalculator

Parameters:

edge - The edge.

Returns:

The weight of the edge.

getOrderWeight

public double getOrderWeight(Edge edge,
                             java.util.List<Cycle> cycles)

Description copied from interface: WeightCalculator

Gets the weight of the edge for ordering the most promising edges to remove. A promising edge will be likelier to be removed early, as its potential for being part of the minimal feedback arc set is high.

Specified by:

getOrderWeight in interface WeightCalculator

Parameters:

edge - The edge to check for.

cycles - The list of cycles which were found in the graph.

Returns:

The weight of the edge for ordering of most promising edges to remove.
