WebIn graph theory terms, a regular projection of a knot, or knot diagram is thus a quadrivalent planar graph with over/under-decorated vertices. The local modifications of this graph which allow to go from one diagram to any other diagram of the same knot (up to ambient isotopy of the plane) are called Reidemeister moves. WebOct 8, 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates.

WebApr 6, 2024 · Terminologies of Graph Theory. A non-trivial graph includes one or more vertices (or nodes), joined by edges. Each edge exactly joins two vertices. The degree of a vertex is defined as the number of edges joined to that vertex.
