In graph theory, path coloring usually refers to one of two problems: * The problem of coloring a (multi)set of paths in graph , in such a way that any two paths of which share an edge in receive different colors. Set and graph are provided at input. This formulation is equivalent to vertex coloring the conflict graph of set , i.e. a graph with vertex set and edges connecting all pairs of paths of which are not edge-disjoint with respect to . * The problem of coloring (in accordance with the above definition) any chosen (multi)set of paths in , such that the set of pairs of end-vertices of paths from is equal to some set or multiset , called a set of requests. Set and graph are provided at input. This problem is a special case of a more general class of graph routing problems, known as . In both the above problems, the goal is usually to minimise the number of colors used in the coloring. In different variants of path coloring, may be a simple graph, digraph or multigraph.

What is a Path Graph? | Graph Theory
What is a path graph? We have previously discussed paths as being ways of moving through graphs without repeating vertices or edges, but today we can also talk about paths as being graphs themselves, and that is the topic of today's math lesson! A path graph is a graph whose vertices can

What is a Path? | Graph Theory
What is a path in the context of graph theory? We go over that in today's math lesson! We have discussed walks, trails, and even circuits, now it is about time we get to paths! Recall that a walk is a sequence of vertices in a graph, such that consecutive vertices are adjacent. A path is t

What is a Walk? | Graph Theory
What is a walk in the context of graph theory? That is the subject of today's math lesson! A walk in a graph G can be thought of as a way of moving through G, where you start at any vertex in the graph, and then move to other vertices through the edges in the graph. In a walk, you are allo
