AlgoEvo: Self-Evolving Agentic Search for Automated Algorithm Discovery

AlgoEvo is introduced, a unified agentic architecture that transforms automated algorithm discovery into an interactive, knowledge-accumulating process, demonstrating strong intra-task accumulation, cross-task transfer, and the ability to reproduce or exceed the strongest existing methods through flexible skill activat...

Test-Time Scaling via Budgeted Multi-Attribute Verification

Verifying LLM-generated answers under a shared computational budget requires jointly deciding which candidates to inspect and which verification attributes to evaluate. We formulate this problem as multi-attribute good-arm identification under a global budget: each candidate is an arm evaluated along several costly att...

Neural Evolution Strategy for Black-box Pareto Set Learning

This work proposes leveraging evolution strategies (ESs), a class of specialized black-box optimization algorithms, within the PSL paradigm, by encapsulating the dependencies within a neural network, which is then trained using a novel gradient estimation method.
