WebMar 21, 2024 · Graph theory is an area of mathematics that has found many applications in a variety of disciplines. Throughout this text, we will encounter a number of them. However, graph theory traces its origins to a problem in Königsberg, Prussia (now Kaliningrad, Russia) nearly three centuries ago. 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. 6.

WebOdd cycle transversal is an NP-complete algorithmic problem that asks, given a graph G = (V,E) and a number k, whether there exists a set of k vertices whose removal from G would cause the resulting graph to be bipartite. The problem is fixed-parameter tractable, meaning that there is an algorithm whose running time can be bounded by a polynomial function … WebAug 22, 2024 · 1. 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. A cycle is a walk in which the end vertex is the same as the ...

A chordless cycle in a graph, also called a hole or an induced cycle, is a cycle such that no two vertices of the cycle are connected by an edge that does not itself belong to the cycle.

WebDec 23, 2024 · Definition 1: A graph, G, is acyclic if it contains no undirected cycles (otherwise it’s cyclic). It also says Definition 2: A (directed) cycle is a (directed) path which begins and ends at the same vertex. An undirected cycle is, likewise, a path beginning and ending at the same vertex which may or may not respect edge directions.
