Efficient Heuristics Generation for Solving Combinatorial Optimization Problems Using Large Language Models

1 code implementation19 May 2025 Xuan Wu, Di Wang, Chunguo Wu, Lijie Wen, Chunyan Miao, Yubin Xiao, You Zhou

To reduce computing resources required for evaluating the derived heuristics, we propose few-shot Performance Prediction Prompting (PPP), a first-of-its-kind method for the Heuristic Generation (HG) task.

Maximal Margin Distribution Support Vector Regression with coupled Constraints-based Convex Optimization

no code implementations5 May 2019 Gaoyang Li, Jinyu Yang, Chunguo Wu, Qin Ma

Recent researchers reveal that maximizing the margin distribution of whole training dataset rather than the minimal margin of a few support vectors, is prone to achieve better generalization performance.
