It is guaranteed that each node of the graph is connected by the edges with at least k other nodes of the graph. Output In the first line print integer r (r ≥ k + 1) — the length of the found cycle. In the next line print r distinct integers v1, v2, ...,...
A cycle in a Graph is a path that starts and ends at the same vertex, where no edges are repeated. It is similar to walking through a maze and ending up exactly where you started.F B C A E D G Is cyclic: DFS Cycle Detection ...

Any cycle of a graph can be expressed as a sum modulo 2 over a fundamental cycle set of the graph (Gould 1959, Paton 1969). The minimum number of swaps between vertices in a random circular embedding of a cycle to put in its standard configuration is considered by Björner and Wachs...
We prove that for every c >0 there exists a constant K = K ( c ) such that every graph G with n vertices and minimum degree at least c n contains a cycle of length t for every even t in the interval [4, e c ( G ) K ] and every odd t in the interval [ K , o c (...
这里我们可以用 networkx 库来做, 很简单,创建 Graph 之后: cycles = nx.cycle_basis(G) 实际上找所有的 cycle 也可以用 networkx 来做,此处的代码 cycles.py 能work,好,来看 cube 的 cycle basis: 四个面 cycle ,再加上底下的这个 cycle, 不知道定义里面的这个 “any cycle in the network can be wri...
