A distributed simplex algorithm for degenerate linear programs and multi-agent assignments

open access: yes, 2012
In this paper we propose a novel distributed algorithm to solve degenerate linear programs on asynchronous peer-to-peer networks with distributed information structures.

Multiechelon Spare Parts Inventory Optimization for Offshore Wind Farm Maintenance: A Decision‐Support Framework for Engineering Managers

open access: yesWind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT Offshore wind farm operations depend on timely access to critical spare parts, yet maintenance planning is constrained by long procurement lead times, weather‐limited site access, and geographically distributed storage facilities. This study presents a practically oriented multiechelon spare parts inventory planning framework that supports ...

Developments in linear and integer programming

open access: yes, 2002
In this review we describe recent developments in linear and integer (linear) programming. For over 50 years Operational Research practitioners have made use of linear optimisation models to aid decision making and over this period the size of problems ...

Upscaling the Strength Domain of Heterogeneous Cohesive‐Frictional Materials via a General FFT‐Based Limit Analysis Approach

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.
ABSTRACT Limit analysis and yield design provide a well‐defined mathematical framework for upscaling the strength properties of heterogeneous materials. These techniques can be incorporated into an FFT‐based computational micromechanics framework to evaluate the strength of heterogeneous materials, based on images of their microstructure.

A Study of Degeneracy in the Simplex Algorithm for Linear Programming and Network Flow Problems (Optimization, Mathematical).

open access: yes, 1984
Degeneracy has been the subject of much research in the field of mathematical programming, since it is related to the computational efficiency of the simplex algorithm.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, Volume 16, Issue 6, Page 1102-1114, June 2026.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Strongly polynomial primal monotonic build-up simplex algorithm for maximal flow problems [PDF]

open access: yes, 2015
The maximum flow problem (MFP) is a fundamental model in operations research. The network simplex algorithm is one of the most efficient solution methods for MFP in practice.
