Many heuristic approaches have been proposed in the literature for the multiple length cutting stock problem, while only few results have been reported for exact solution algorithms. In this paper, we present a new branch-and-price-and-cut algorithm which outperforms other exact approaches proposed...

In order to evaluate the proposed distribution policies, Archetti et al. (2016) carried out worst-case as well as experimental analyses. In particular, they devised exact and heuristic algorithms. The tests were run on 64 small instances, with 15 customers and up to three commodities, 80 mid...
This paper provides a tutorial on Branch-Price-and-Cut (BPC) algorithms for a generic class of problems whose objective is to find a set of feasible paths in a graph while optimising a given objective function. The tutorial is split into two main parts. First, we describe the building bloc...
• COIN/BCP is focused on the implementation of ful l-blown branch( cut)and price algorithms. •The framework centers around the management of classes of dynamical ly generated cut and variables, generical ly cal led objects. • Subproblems are composed of dynamic l ists of these objects...
evolutionary algorithms [9] and enumerative schemes, both LP [7, 31] and non-LP based [20, 29]. However, for CSP where the right-hand side is large, LP-based exact methods have been more effective. In the last years many efforts have been successful to solve CSP exactly by an...

In addition, the branching and price cutting algorithms successfully solve the optimal problem of the case in a reasonable time. We are surprised to find that when the uncertainty level is low, even Γ = 5. The cost increase is also less than the high uncertainty level with Γ = 3. This...
This work presents a sophisticated exact algorithm for the TSPHS, a Branch-Cut-and-Price (BCP) algorithm that includes and adapts several features found in state-of-the-art algorithms for vehicle routing. In that algorithm, columns correspond to possible salesperson day trips; subtour elimination ...
(2019), introducing new algorithms that improve the quality of the solutions. Another interesting aspect deals with access to the recharging infrastructure. The limited capacity of a recharge station (in terms of chargers) may be exceeded by the high demand of vehicles during peak hours. This ...
