Oriented cycles
Witrynamay also consider other n-vertex oriented cycles. An oriented cycle is any digraph formed by taking an undirected cycle and orienting its edges. Ferber and Long [7] … WitrynaAn oriented cycle is an orientation of a undirected cycle. We first show that for any oriented cycle C, there are digraphs containing no subdivision of C (as a subdigraph) …

Witrynaj=1 Yj is a source map with the Yj indecomposable and X on an oriented cycle in Γ A, then t ≤ 4 and at most three of the Yj are not projective. The dual statement for a sink map holds. Finally, if an arrow X → Y in Γ A with valuation (d,d0) is on an oriented cycle, then dd0 ≤ 3. Let A be a fixed Artin algebra, modA the category of ... Witryna4 lis 2008 · A directed graph G is acyclic if and only if a depth-first search of G yields no back edges. This has been mentioned in several answers; here I'll also provide a code example based on chapter 22 of CLRS. The example graph is illustrated below. CLRS' pseudo-code for depth-first search reads:

Combining methods in [10] with Theorem 1.1, we know that, for stable equivalences induced by exact functors, the above condition “no nodes” can be removed. 2.

Witryna1 wrz 2008 · We show that for each α>0 every sufficiently large oriented graph G with δ + ( G ), δ − ( G )≥3 G /8+α G contains a Hamilton cycle. This gives an approximate solution to a problem of Thomassen [21]. In fact, we prove the stronger result that G is still Hamiltonian if δ ( G )+δ + ( G )+δ − ( G )≥3 G /2 + α G .

All the back edges which DFS skips over are part of cycles. In an undirected graph, the edge to the parent of a node should not be counted as a back edge, but finding any other already visited vertex will indicate a back edge. In the case of undirected graphs, only O(n) time is requi… male reproductive system biology
