Web8 jan. 2024 · A k-factor of a graph G= (V,E) is a k -regular subgraph with vertex set V. Note that a 2-factor of G is a collection of simple vertex-disjoint cycles covering all vertices of G, that is a cycle cover. We denote by C^* a maximum weight cycle cover for G. If G is a multigraph, C^* might contain cycles of length 2. WebK-Factors are calibration values (pulses per unit of volume) used to convert flow sensor output frequencies to flow rates.

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. A k-regular graph is 1-factorable if it has chromatic index k; examples of … Meer weergeven If a graph is 2-factorable, then it has to be 2k-regular for some integer k.

In this problem, the (weighted) k -regular graph is hidden (planted) by adding new weighted edges to it. The weights of the planted and non-planted edges are random quantities with different distributions.

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. WebThe K-factor is defined as the distribution of the component between the hydrate and the gas ( Carroll, 2014 ): (8.69) in which yi and xi stand for the mole fractions of component i in the vapor and hydrate, correspondingly. These mole fractions are on a water-free base and water is not involved in the computations.
