WebJul 17, 2024 · 1. Select the cheapest unused edge in the graph. 2. Repeat step 1, adding the cheapest unused edge to the circuit, unless: a. adding the edge would create a circuit that doesn’t contain all vertices, or. b. adding the edge would give a vertex degree 3. 3. Repeat until a circuit containing all vertices is formed. photography datasetWebOct 17, 2024 · Graph G ( V, E) is a fully connected mesh in which each node is connected to all other nodes.
