In mathematics, avertex cycle cover (commonly called simply cycle cover) of a graph isthe set of cycles which are subgraphs of G and contain all vertices ofG. If the cycles of the cover have no vertices in common, the cover iscalled vertex-disjoint or sometimes simply disjoint cycle cover. In thiscase the set of the cycles constitutes a spanning subgraph of G. If thecycles of the cover have no edges in common, the cover is callededge-disjoint or simply disjoint cycle cover. Similar definitions may beintroduced for digraphs, in terms of directed cycles. The permanent of a01-matrix is equal to the number of cycle covers of a directed graphwith this adjacency matrix. This fact is used in a simplified proof ofthe fact that computation of the permanent is #P-complete.…

In the mathematical discipline of graph theory, a vertex cover of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. The problem of finding a minimum vertex cover is a classical optimization problem in computer science and is a typical example of an NP-hard optimization problem that has an approximation algorithm. Its decision version, the vertex cover problem was one of Karp's 21 NP-complete problems and is therefore a classical NP-complete problem in computational complexity theory. Furthermore, the vertex cover problem is fixed-parameter tractable and a central problem in parameterized complexity theory. The minimum vertex cover problem can be formulated as a half-integral linear program whose dual linear program is the maximum matching problem.…
