WebbA simple example of a directed graph with negative-weight edges for which Dijkstra's algorithm produces incorrect answers is shown below: A -> B: -2. B -> C: 4. C -> A: -3. The proof of correctness for Dijkstra's algorithm relies on the assumption that all weights are non-negative. Since this graph has edges with negative weights, Dijkstra's ...

"WebbIn a simple graph with n number of vertices, the degree of any vertices is − deg (v) ≤ n – 1 ∀ v ∈ G A vertex can form an edge with all other vertices except by itself. So the degree of a vertex will be up to the number of vertices in the graph minus 1. This 1 is for the self-vertex as it cannot form a loop by itself. " - Simple directed graph
