In graph theory, a factor of a graph G is a spanning subgraph, i.e., a subgraph that has the same vertex set as G. A k-factor of a graph is a spanning k-regular subgraph, and a k-factorization partitions the edges of the graph into disjoint k-factors. A graph G is said to be k-factorable if it admits a k … Meer weergeven If a graph is 1-factorable (i.e., has a 1-factorization), then it has to be a regular graph. However, not all regular graphs are 1-factorable.

Web18 jun. 2015 · Factoring complete graphs is completely solved by the "Walecki construction" (Google is your friend). It says that K 2 n + 1 has a decomposition in n Hamiltonian cycles and K 2 n has a decomposition in n − 1 Hamiltonian cycles and a perfect matching. This means that for even n you can build any factor you like. WebIf a connected graph is 2 k -regular it may be k -factored, by choosing each of the two factors to be an alternating subset of the edges of an Euler tour.
