Reformulation and decomposition of integer programs [PDF]

In this survey we examine ways to reformulate integer and mixed integer programs. Typically, but not exclusively, one reformulates so as to obtain stronger linear programming relaxations, and hence better bounds for use in a branch-and-bound based ...

Graph‐based imitation and reinforcement learning for efficient Benders decomposition

AIChE Journal, Volume 72, Issue 6, June 2026.
Abstract This work introduces an end‐to‐end graph‐based agent for accelerating the computational efficiency of Benders Decomposition. The agent's policy is parameterized by a graph neural network, which takes as input a bipartite graph representation of the master problem and proposes a candidate solution.

Robustness Assessment of Public Transport Networks in Various Graph Representations: Systematic Review, Decision Support, and Case Study

Networks, Volume 87, Issue 4, Page 343-371, June 2026.
ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.

Beautiful and Useful: Species Richness and the Ecosystem Services of Allotment Gardens in Berlin, Germany

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Intensive agriculture and urbanization have led to habitat degradation and fragmentation, reducing plant diversity and subsequently reducing pollinator abundance and richness. This paper investigates the conservation potential of green infrastructure in allotment gardens, which are a common form of urban land use.

iLDA‐SGCN: Identifying Associations Between Age‐Related Diseases and Long Non‐Coding RNAs Using Dual Graph Convolutional Networks

Aging Cell, Volume 25, Issue 6, June 2026.
iLDA‐SGCN integrates singular value decomposition and dual graph convolutional networks to predict lncRNA‐disease associations. It achieves superior performance on two benchmark datasets and identifies 33 candidate lncRNAs across 8 age‐related diseases.

Post‐transcriptional regulatory networks: The dynamic interplay of RNA‐binding proteins

The FEBS Journal, Volume 293, Issue 12, Page 3423-3441, June 2026.
Post‐transcriptional gene expression regulation is controlled by RNA‐binding proteins (RBPs), which influence many processes including splicing, localization, translation, and decay. Rather than acting alone, RBPs bind RNAs combinatorially, forming complex, context‐dependent regulatory networks.
