AI that auto-builds large-scale optimization models (LEAN-LLM-OPT)

Big business decisions often rely on complex optimization models, but building them is slow and manual. Meet LEAN-LLM-OPT, a lightweight, multi-agent AI that auto-formulates large-scale optimization models from a plain-English problem description and datasets. How it works: two planner agents design a step-by-step workflow for similar problems; a builder agent

Smarter, Risk-Aware Route Planning for Utility Crews

Why it matters Utility crews rarely know exactly how long each job will take. This paper blends machine learning and risk-aware optimization to plan daily routes that stay on time—even when jobs run long. Using eight years of gas meter maintenance data, the author trains a gradient-boosted model (XGBoost)
