EdgeChromaticNumber (Combinatorica Package Symbol)

EdgeChromaticNumber[g] gives the fewest number of colors necessary to color each edge of graph g, so that no two edges incident on the same vertex have the same color.

EdgeColoring (Combinatorica Package Symbol)

EdgeColoring[g] uses Brelaz's heuristic to find a good, but not necessarily minimal, edge coloring of graph g.

EdgeColor (Combinatorica Package Symbol)

EdgeColor is an option that allows the user to associate colors with edges. Black is the default color. EdgeColor can be set as part of the graph data structure or in ...

EdgeDirection (Combinatorica Package Symbol)

EdgeDirection is an option that takes on values True or False allowing the user to specify whether the graph is directed or not. EdgeDirection can be set as part of the graph ...

EdgeLabelColor (Combinatorica Package Symbol)

EdgeLabelColor is an option that allows the user to associate different colors to edge labels. Black is the default color. EdgeLabelColor can be set as part of the graph data ...

EdgeLabelPosition (Combinatorica Package Symbol)

EdgeLabelPosition is an option that allows the user to place an edge label in a certain position relative to the midpoint of the edge. LowerLeft is the default value of this ...

EdgeWeight (Combinatorica Package Symbol)

EdgeWeight is an option that allows the user to associate weights with edges. 1 is the default weight. EdgeWeight can be set as part of the graph data structure.

EmptyGraph (Combinatorica Package Symbol)

EmptyGraph[n] generates an empty graph on n vertices. An option Type that can take on values Directed or Undirected is provided. The default setting is Type -> Undirected.

EmptyQ (Combinatorica Package Symbol)

EmptyQ[g] yields True if graph g contains no edges.

EquivalenceClasses (Combinatorica Package Symbol)

EquivalenceClasses[r] identifies the equivalence classes among the elements of matrix r.
