Research Topics
Single-objective optimization and its applications: mainly develop efficient optimization algorithm to solve large-scale optimization problems with differnet characteristics, including contraint nonlinear programming (NLP) problems, mixed-integer nonlinear programming (MINLP) problems, and expensive optimization problems. The following directions are summarized:
1. Large-scale optimization: Aim to develop high-efficient optimization algorithms to resolve high-dimensional NLP, MINLP, or other constraint engineering optimization problems.
2. Expensive single-objective optimization: Aim to construct cheap meta-model or surrogate model to replace the expensive objective function, aiming to improve the efficiency of the optimization.
3. Various applications: Large-scale Crude Oil Scheduling Problems, Welded Beam Design, Tension/Compression Spring Design, Pressure Vessel Design, Power Dispatch, etc.
Multi-/many-objective optimization and its applications: mainly design efficient multi-objective evolutionary algorithms (MOEAs) to solve many-objective optimization problems, dynamic multi-objective problems, constraint multi-objective problems, expensive multi-objective problems, multi-task optimization problems, variable-length mixed-variable multi-objective optimization problems. The following directions are concluded:
1. Preference-driven multi-objective optimization: Aim to facilitate the decision makers in decision making by learning their explicit or implicit preferences in sovling the real applications, such as the crude oil scheduling and hybrid electrical vehicles controller design.
2. Multi-objective or many-objective optimization: Aim to develop novel frameworks of MOEAs to achieve a good representative solution set to the Pareto optimal front (PF) or desired regions of interest (SOIs) of the multi-objective problems on different cases that the number of objectives is high, the optimization environment is dynamicly changing, and the problem with multiple types of decision variables (e.g., the continuous and discrete variables) with a variable-length structure (i.e., the number of the decision variables is unknown beforehand).
3. Expensive multi-objective optimization: In most practical problems, the objective function estimation is expensive. The main research aims to design efficient data-driven evolutionary algorithms to solve the actual costly optimization problems, such as such as the crude refining process and combustion model optimization.
4. Evolutionary multi-task optimization: Aim to introduce transfer learning or other machine learning techniques to assist in simultaneously handling multiple tasks.
