Right Answers, Costly Models: The Efficiency Gap in LLM-based Optimization Modeling

Zhong Li, Xin Huang, Jinhui Wan et al. · 2026

Optimization modeling formulates real-world decision problems as mathematical programs that solvers can use to find optimal decisions. Large language models (LLMs) can automate this process, but the resulting correct formulations can require substantial time and memory to construct and solve, limiting practical scalabi …

Does Native 3D Texture Generation Necessarily Require 3D Assets for Training?

Jiangshan Wang, Zeqiang Lai, Jiayi Guo et al. · 2026

Native 3D texture generation synthesizes colors directly in 3D space for a given geometry, conditioned on multi-view reference images. It is generally believed that training such models requires large-scale, high-quality real 3D asset data, whose acquisition remains a long-standing and challenging problem. In this work …
