In the tree representation, we can do DFS of tree. If we reach a point where a solution no longer is feasible, there is no need to continue exploring. In the given example, backtracking would be much more effective if we had even more items or a smaller knapsack capacity.

WebIn many algorithms, backtracking means: try one option and see where it leads, then go back to that decision point and try taking the other option. Repeat for as many options as there are. Compare the outcomes of all of these options and pick the best. Sometimes you just need to find a solution, not the best one.
