BDDs in a Branch and Cut Framework [PDF]

open access: yes, 2005
Branch & Cut is today's state-of-the-art method to solve 0/1-integer linear programs. Important for the success of this method is the generation of strong valid inequalities, which tighten the linear programming relaxation of 0/1-IPs and thus allow for early pruning of parts of the search tree.

Pruning by Isomorphism in Branch-and-Cut

open access: yesMathematical Programming, 2001
The paper presents a branch-and-cut for solving (0, 1) integer linear programs having a large symmetry group. The group is used for pruning the enumeration tree and for generating cuts. The cuts are non-standard, cutting integer feasible solutions but leaving the optimal value of the problem unchanged.

Exploiting planarity in separation routines for the symmetric travelling salesman problem [PDF]

open access: yes, 2008
At present, the most successful approach to solving large-scale instances of the Symmetric Traveling Salesman Problem to optimality is branch-and-cut.

Exploiting sparsity in pricing routines for the capacitated arc routing problem [PDF]

open access: yes, 2009
The capacitated arc routing problem (CARP) is a well-known and fundamental vehicle routing problem. A promising exact solution approach to the CARP is to model it as a set covering problem and solve it via branch-cut-and-price.

Solving the Traveling Salesman Problem with release dates via branch and cut

open access: yesEURO Journal on Transportation and Logistics, 2023
In this paper we study the Traveling Salesman Problem with release dates (TSP-rd) and completion time minimization. The TSP-rd considers a single vehicle and a set of customers that must be served exactly once with goods that arrive to the depot over ...

The Branch and Cut Method for Solving Capacitated Vehicle Routing Problem (CVRP) Model of LPG Gas Distribution Routes

open access: yesScience and Technology Indonesia, 2019
Capacitated Vehicle Routing Problem (CVRP) is a problem that discusses how to choose several routes that must be passed by a number of transport vehicles in the process of distributing goods that combine customer demand with regard to transport capacity.

An Effective Branch-and-cut algorithm in Order to Solve the Mixed Integer Bi-level Programming

open access: yesInternational Journal of Production Management and Engineering, 2017
In this paper, a new branch-and-cut algorithm for mixed integer bi-level programming is proposed. For achieving this purpose, a historical perspective of the development of enumeration methods in the field of bi-level linear programming is considered ...

A Wheeler–DeWitt Non-Commutative Quantum Approach to the Branch-Cut Gravity

open access: yesUniverse, 2023
In this contribution, motivated by the quest to understand cosmic acceleration, based on the theory of Hořava–Lifshitz and on the branch-cut gravitation, we investigate the effects of non-commutativity of a mini-superspace of variables obeying the ...

Separating valid odd-cycle and odd-set inequalities for the multiple depot vehicle scheduling problem

open access: yesEURO Journal on Computational Optimization, 2013
We consider the multicommodity network flow formulation of the multiple depot vehicle scheduling problem (MDVSP) and investigate several strategies within a branch-and-cut framework for solving the MDVSP.
