Minimum cycle basis c++

The minimum weight cycle basis of a nearest neighbor graph of points sampled from a three-dimensional surface can be used to obtain a reconstruction of the surface. In cheminformatics, the minimal cycle basis of a molecular graph is referred to as the smallest set of smallest rings. References Meer weergeven In graph theory, a branch of mathematics, a cycle basis of an undirected graph is a set of simple cycles that forms a basis of the cycle space of the graph. That is, it is a minimal set of cycles that allows every even-degree subgraph … Meer weergeven Several special types of cycle bases have been studied, including the fundamental cycle bases, weakly fundamental cycle bases, sparse (or 2-) cycle bases, and integral cycle bases. Induced cycles Every graph … Meer weergeven Cycle bases have been used for solving periodic scheduling problems, such as the problem of determining the schedule for a public transportation system.
