4.2. Branch and Bound Algorithm Pseudocode Now let’s discuss how to solve the job assignment problem using a branch and bound algorithm. Let’s see the pseudocode first: algorithm MinCost(M): // INPUT // M = The cost matrix // OUTPUT // The optimal job assignment minimizing the total...
With respect to this pseudocode, the search strategy affects the order in which nodes are selected for exploration in Line 3 of Algorithm 1; the branching strategy affects the number of children and the way the subproblem is partitioned (Line 6, Algorithm 1), and the pruning rules in Line ...
the solution space is often too vast to traverse. The branch-and-bound algorithm handles this problem byboundingandpruning. Bounding refers to setting a bound on the solution quality (e.g., the route length
Please note, in the final line of the pseudocode, that we return\((F_1, F_2, \ldots , F_k)\)rather than\((F_1, F_2, \ldots , F_K)\). This is because the training procedure can potentially stop earlier, when\(k<K\), provided that the final requirements (A,D) for the...

As rapid response to changes becomes more imperative, optimization under uncertainty has continued to grow in both the continuous and mixed-integer fields. We design a branch-and-bound (BB) algorithm for mixed-binary nonlinear optimization problems with parameters in general locations. At every node...

While constrained, multiobjective optimization is generally very difficult, there is a special case in which such problems can be solved with a simple, elegant branch-and-bound algorithm. This special case is when the objective and constraint functions are Lipschitz continuous with known Lipschitz con...
