WebBranch And Bound. Branch and bound is an extension of backtracking, which adds the notion of optimality. It allows the user to specify a notion of “goodness”, which it can optimize for when searching for solutions. Instead of stopping when a solution is found, it continues to search the space for a more optimal solution.
