Position analysisBranch-and-prune algorithmsDifferent branch-and-prune schemes can be found in the literature for numerically solving the position analysis of spherical mechanisms. For the prune operation, they all rely on the propagation of......
Branch and bound (BB, B&B, or BnB) is an algorithm design paradigm for discrete and combinatorial optimization problems, as well as mathematical optimization. A branch-and-bound algorithm consists of a systematic enumeration of candidate solutions by means of state space search: the set of candida...
the branch is checked against upper and lower estimated bounds on the optimal solution, and is discarded if it cannot produce a better solution than the best one found so far by the algorithm.
N_i above for (auto&& child_branch : node.candidate_nodes) { if (lower_bound_function(child_branch) <= problem_upper_bound) { candidate_queue.enqueue(child_branch); // Step 3.3.2 } // otherwise, g(N_i) > B so we prune the branch; step 3.3.1 } } } return current_optimum; ...
This section also discusses extensions to B&B such as branch-and-cut or branch-and-price, which both serve to improve the pruning rules used in the search procedure. Finally, Section 6 provides some concluding remarks. 2. Branch-and-bound 2.1. Algorithm overview Define an optimization problem ...

This paper presents three techniques for using an iter- ated local search algorithm to improve the performance of a state-of-the-art branch and bound algorithm for job shop scheduling. We use iterated local search to obtain (i) sharpened upper bounds, (ii) an improved branch- ordering heurist...

Branches only Only branch generators factor into the shape control algorithm. All descendants Every generator that is a descendant of the generator initiating shape control influences the length of branches under shape control. Distribution Distribution lets you push and pull the relative lengths from on...
