Diversity-Driven Offline Multi-Objective Optimization via Bi-Level Pareto Set Learning

ICML 2026poster

Multi-objective optimization (MOO) has emerged as a powerful approach to solving complex optimization problems involving multiple objectives. In many practical scenarios, function evaluations are unavailable or prohibitively expensive, necessitating optimization solely based on a fixed offline datas…

Constrained Offline Black-Box Optimization via Risk Evaluation and Management

AAAI 2025technical

Offline black-box optimization aims to identify the optimal solution of a black-box objective function under the guidance of a surrogate model constructed solely from a pre-collected dataset. It is commonly used in industrial scenarios, which often involve constraints, i.e., constrained offline opti…

Relation-Augmented Dueling Bayesian Optimization via Preference Propagation

IJCAI 2025

In black-box optimization, when directly evaluating the function values of solutions is very costly or infeasible, access to the objective function is often limited to comparing pairs of solutions, which yields dueling black-box optimization. Dueling optimization is solely based on pairwise preferen

SOO-Bench: Benchmarks for Evaluating the Stability of Offline Black-Box Optimization

ICLR 2025poster

Black-box optimization aims to find the optima through building a model close to the black-box objective function based on function value evaluation. However, in many real-world tasks, such as the design of molecular formulas and mechanical structures, it is perilous, costly, or even infeasible to e…
