Greedy coloring
WebApr 10, 2024 · Graph Coloring implementation in traffic routing. I want to use greedy algorithm for traffic phase allocation in road junction . But the problem is the greedy algorithm gives me a result that colored vertices (represent routs) those have same origin route (suppose AB route is V1 vertex, AC route is V2 vertex here both have origin A) … WebJan 22, 2014 · The greedy coloring algorithm assigns a color (non-negative integer) c(x) to each vertex xin a greedy manner as follows. The variable kstores the number of colors used; this will be the output. Notation: adj(i) is the list of vertices adjacent to vertex i. 0 k:= 0 1 for i= 1 to ndo
