Finding the global optimal solution in Dynamic multiple TSPTW with data-driven ACO

2021

Dynamic Travelling Salesman Problem (D-TSP) is a classic dynamic optimization problem (DOP), which aims to maintain the optimal route with every change of the graph. D-TSP often greedily pursues the current optimum after each change …

PREE: Towards Harmless and Adaptive Fingerprint Editing in Large Language Models via Knowledge Prefix Enhancement

2025 · arXiv (Cornell University)

Addressing the intellectual property protection challenges in commercial deployment of large language models (LLMs), existing black-box fingerprinting techniques face dual challenges from incremental fine-tuning erasure and feature-space defense due to their reliance on overfitting high-perplexity …
