The branch and bound algorithm works by dividing a problem into smaller subproblems or branches, and at each branch, it uses both upper and lower bounds to determine if it is worthwhile to explore further or if the branch can be pruned. The lower bound helps to create an initial estimate of the solution, while the upper bound helps to determine a maximum limit beyond which no solution can be found. By using both bounds, the algorithm can reduce the search space and find the optimal solution efficiently. Therefore, the best choice is to use both upper and lower bounds.
