$\begingroup$ "Also by Axiom 1, we can see that a graph with n-1 edges has one component, which implies that the graph is connected" - this is false. Axiom 1 states that a graph with n vertices and n-1 edges has AT LEAST n-(n-1)=1 component, NOT 1 component. The proof is almost correct though: if the number of components is at least n …There is (as far as I know) no simple solution. You must assume some voltage between the nodes of interest, and then write down ohms law for each resistor in the graph, and current conservation equations for each node. For a graph with \$n\$ nodes, you will get \$n\$ current conservation equations, and \$n^2\$ resistance equations.The graphical model of an RBM is a fully-connected bipartite graph.

An example with N = 4 is shown in Fig. 4.You could pass a pointer to an array containing all the nodes. You could pass just the one starting node and work from there, if it's a fully connected graph. And finally, you could write a graph class with whatever data structures you need inside it, and pass a reference to an instance of that class.The advantage of taking the combinations, is that we only need to iterate once over the components, and we ensure that on each iteration, previously seen components are ignored, since in combinations order does not matter, i.e. if we've seen the combination (1,2) we won't be seing (2,1), which could lead to two components being connected …Properties of Complete Graph: The degree of each vertex is n-1. The total number of edges is n(n-1)/2. All possible edges in a simple graph exist in a complete graph. It is a cyclic graph. The maximum distance between any pair of nodes is 1.
