Webb17 feb. 2024 · Simple Graph; In contrast to a multigraph, a simple graph is an undirected graph in which multiple edges and loops are forbidden. Every vertex in a simple graph with n vertices has a degree of n-1. Weighted Graph; Every edge in a weighted graph has a value (weight) associated with it. Instead of weight, we can use the phrases cost or length.
