The statement that G is acyclic if and only if the number of edges is at least n- (n-rank (L))+1 is obviously wrong ( at least should be at most perhaps) – Pushpendre Apr 23, 2015 at 6:52 WebIn an undirected simple graph, there are no self loops (which are cycles of length 1) or parallel edges (which are cycles of length 2). Thus all cycles must be of length at least 3. And a simple path can't use the same edge twice, so A -to- B -to- A doesn't count as a cycle of length 2. A path is simple if all edges and all vertices on the path ... hertz music converter

"WebIn 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 to be expressed as a symmetric difference of basis cycles. " - Cycle in a undirected graph
