Buffer capacity allocation in unreliable production lines: An adaptive large neighborhood search approach

open access: yesEngineering Science and Technology, an International Journal, 2021
The design of a production line directly affects the system performance which is usually measured by its throughput. The problem involving determination of the optimal capacity and location of the buffers in a production line is known as the buffer ...

A General Large Neighborhood Search Framework for Solving Integer Programs [PDF]

open access: yes, 2020
This paper studies how to design abstractions of large-scale combinatorial optimization problems that can leverage existing state-of-the-art solvers in general purpose ways, and that are amenable to data-driven design.

A machine learning framework for neighbor generation in metaheuristic search

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
This paper presents a methodology for integrating machine learning techniques into metaheuristics for solving combinatorial optimization problems. Namely, we propose a general machine learning framework for neighbor generation in metaheuristic search. We

SLIDER: Mining correlated motifs in protein-protein interaction networks [PDF]

open access: yes, 2009
—Correlated motif mining (CMM) is the problem to find overrepresented pairs of patterns, called motif pairs, in interacting protein sequences. Algorithmic solutions for CMM thereby provide a computational method for predicting binding sites for protein ...

Adaptive large neighborhood search for mixed integer programming [PDF]

open access: yesMathematical Programming Computation, 2021
AbstractLarge Neighborhood Search (LNS) heuristics are among the most powerful but also most expensive heuristics for mixed integer programs (MIP). Ideally, a solver adaptively concentrates its limited computational budget by learning which LNS heuristics work best for the MIP problem at hand.

An Effective Decomposition-Based Stochastic Algorithm for Solving the Permutation Flow-Shop Scheduling Problem

open access: yesAlgorithms, 2021
This paper presents an effective stochastic algorithm that embeds a large neighborhood decomposition technique into a variable neighborhood search for solving the permutation flow-shop scheduling problem. The algorithm first constructs a permutation as a

A GPU-based Iterated Tabu Search for Solving the Quadratic 3-dimensional Assignment Problem [PDF]

open access: yes, 2010
International audienceThe quadratic 3-dimensional assignment problem (Q3AP) is an extension of the well-known NP-hard quadratic assignment problem. It has been proved to be one of the most difficult combinatorial optimization problems.

Large neighborhood local search optimization on graphics processing units [PDF]

open access: yes2010 IEEE International Symposium on Parallel & Distributed Processing, Workshops and Phd Forum (IPDPSW), 2010
Local search (LS) algorithms are among the most powerful techniques for solving computationally hard problems in combinatorial optimization. These algorithms could be viewed as ``walks through neighborhoods'' where the walks are performed by iterative procedures that allow to move from a solution to another one in the solution space.

Identification of probabilistic cellular automata [PDF]

open access: yes, 2003
The identification of probabilistic cellular automata (PCA) is studied using a new two stage neighborhood detection algorithm. It is shown that a binary probabilistic cellular automaton (BPCA) can be described by an integer-parameterized polynomial ...

Hybridizing large neighborhood search and exact methods for generalized vehicle routing problems with time windows

open access: yesEURO Journal on Transportation and Logistics, 2021
Delivery options are at the heart of the generalized vehicle routing problem with time windows (GVRPTW) allowing that customer requests are shipped to alternative delivery locations which can also have different time windows.
