Graph cycle
WebMar 24, 2024 · Cycle detection is a particular research field in graph theory. There are algorithms to detect cycles for both undirected and directed graphs. There are scenarios where cycles are especially undesired. An example is the use-wait graphs of concurrent systems. In such a case, cycles mean that exists a deadlock problem. WebAug 27, 2024 · A cycle is a path in a graph where the first and last vertices are the same. If we start from one vertex, travel along a path and end up at the starting vertex, then this path is a cycle. Cycle detection is the process of detecting these cycles. Figure 5 shows an animation of traversing a cycle. Algorithms

Depth First Traversal can be used to detect a … WebFeb 8, 2009 · An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle.

A path is a walk with no repeated vertices. A trail is a walk with no repeated edges. A tour is a walk that visits every vertex returning to its starting vertex. A tour could visit some vertices more than once. If you visit them exactly once, then the tour is a Hamiltonian cycle.
