Introduction to Backtracking Algorithm. Backtracking is an algorithmic technique whose goal is to use brute force to find all solutions to a problem. WebIntroduction. To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints.
