Graph Algorithm Backtracking . If n is a leaf node, return ˝failure ˛ 3. // assigned distinct are printed. Coloring using backtracking. A tree is obtained showing from www.researchgate.net Create a recursive function that takes current index, number of vertices and output color array. Therefore, it’s commonly used to solve problems with constraints. The term backtracking suggests that if the current solution is not suitable, then backtrack and try other solutions.

Algorithm Dynamic Programming Backtracking . The term backtracking suggests that if the current solution is not suitable, then backtrack and try other solutions. It takes θ (n) time for tracing the solution since tracing process traces the n rows. BackTracking Algorithm Technique and Examples from www.slideshare.net This algorithm is applied to the particular specific types of problems : However, this recursion backtracking is too slow because of the large search space especially if n is large. All cases are exhausting and then compared to get the optimal solution.
