GPU-Accelerated Preprocessing for Large-Scale Linear Programming

GPU-accelerated first-order methods are increasingly effective for solving large-scale linear programs (LPs), yet LP preprocessing remains predominantly CPU-based and can become costly. A key challenge is that dependencies among presolve reductions and frequent modifications to sparse LP data make efficient GPU paralle...

olBlend: Language-Guided Molecular Blend Retrieval with Mixture Odor Prediction

This work proposes olBlend, a language-guided framework for molecular mixture retrieval that uses MixPOM to predict odor probabilities for candidate molecular pairs and stores these predictions for retrieval, and uses a language model to translate each odor description into three types of semantic requirements.
