Multitask Pareto Optimization for Monotone Submodular Problems with Dynamic Constraints

This work focuses on the case where elements within each constraint have uniform cost and shows that this structure leads to small Pareto fronts in the multitasking formulation, which enables solution sharing across tasks and can improve performance compared to running standard evolutionary approaches independently.

Insights from Multi-tasking the EAX Algorithm for the Travelling Salesperson Problem

This paper investigates integrating evolutionary multitasking with Edge Assembly Crossover (MT-EAX) to solve the classical Travelling Salesperson Problem and demonstrates that the advantage of MT-EAX derives from increased diversity through parallel search in early generations, which can be successfully preserved using...

Taming Treewidth DP with Modulators: A General Booster for Graph Heuristics

This work applies TDP to enhance algorithms across diverse paradigms, including evolutionary search, greedy heuristics, and graph-neural-network-based heuristics, and shows that TDP significantly improves performance over the original methods.
