Minibatch Selection via Partition Matroid Constrained Gradient Matching

Researchers introduce PartitionSel, a minibatch selection algorithm that optimizes training of large language models on diverse datasets by balancing convergence speed with domain coverage. The method uses partition-matroid constraints and gradient-matching utilities to reduce redundancy across domains while maintaining computational efficiency, demonstrating improvements over existing approaches on Qwen2.5 and Llama-3 benchmarks.

An Enhanced Large Neighborhood Search Approach for the Capacitated Facility Location Problem with Incompatible Customers

Researchers have developed an enhanced Large Neighborhood Search (LNS) algorithm to solve a variant of the capacitated facility location problem that incorporates customer incompatibilities, where certain customer pairs cannot share the same facility. The new method employs hybrid destroy operators and exact solvers, achieving superior performance over existing metaheuristics on all benchmark instances.

Planning a Community Approach to Diabetes Care in Low- and Middle-Income Countries Using Optimization

Researchers have developed an optimization framework for Community Health Workers in low- and middle-income countries that personalizes diabetes care visits by balancing screening new patients with managing enrolled individuals. The approach, tested on operational data from Indian urban slums, achieved up to 25% reductions in fasting blood glucose levels while accounting for patient motivational states and dropout rates.
