Webwhether a graph is bipartite. The property says that an undirected graph is bi-partite if it can be colored by two colors. The algorithm we present is a modified DFS that colors the graph using 2 colors. Whenever an back-edge, forward-edge or cross-edge is encountered, the algorithm checks whether 2-coloring still holds. function graph-coloring(G) WebA Bipartite graph is a graph whose vertices can be divided into two independent sets (say P P and Q Q) such that every edge u\rightarrow v u → v connects a vertex from the set P P to a vertex in set Q Q or vice-versa. In other words, set P P and Q Q are disjoint sets i.e. i.e. P\cap U=\phi P ∩U = ϕ. Due to this property, there must not ...
