Author: Zaslav Format: TextThe treatment of signed graphs, [[signed+graph]], states that a signed graph is a simple graph with signed edges. That is incorrect. A signed graph is a graph with signed edges. Depending on the situation, the graph may be simple, or it may allow loops or multiple edges (inclusive or), or it may be whatever else is needed.
