The Speech title: Automated creation of evolutionary algorithms from scratch

Abstract: In recent years, numerous evolutionary algorithms have been proposed to solve various optimization problems. These evolutionary algorithms are mostly manually designed, based on common modules such as genetic operators and differential evolution operators. In this presentation, we propose an automated evolutionary algorithm creation framework that can generate entirely new evolutionary algorithms from scratch. Experiments have shown that the algorithms created by this framework outperform existing algorithms on single-objective, multi-objective, and combinatorial optimization problems. Moreover, they even outperform surrogate-assisted algorithms on expensive optimization problems without using surrogate models. Besides, we have developed a new GUI in PlatEMO v4.8, allowing users to build their own evolutionary algorithms without writing any code and easily surpass existing evolutionary algorithms.

The Speech title: Evolutionary Large-scale Multiobjective Optimization: Challenges and Opportunities

Abstract: Evolutionary algorithms (EAs) have been a popular optimization tool for decades, which have shown promising performance in solving various benchmark optimization problems. Nevertheless, using EAs on problems with over 100 decision variables (large-scale optimization problems, LSOPs) remains challenging due to the "curse of dimensionality", especially for those LSOPs in real-world applications. In this presentation, some EAs for handling the challenges regarding the computational efficiency, balanced performance, and constraints are first introduced. Then, some real-world applications of modelling and solving LSMOPs are explicated. Eventually, some open questions regarding the opportunities of EAs with the assistance of advanced learning models (such as physics-informed neural network and large language models) are discussed.

The Speech title: Evolutionary Multi-objective Feature Selection for Machine Learning

Abstract: Maximizing classification accuracy and minimizing the number of selected features are the two primary objectives in feature selection, making it a multi-objective task. Multi-objective feature selection not only reduces dimensionality and improves accuracy, but also provides insights from complex data. Despite significant advancements, there are still some challenges that need to be addressed, such as complex feature interactions, exponentially growing search space, solution duplication in the objective space, and objective selection bias. In this talk, we will introduce recent works addressing these challenges and highlight emerging directions for the future of multi-objective feature selection.

The Speech title: Neural network-assisted evolutionary algorithm for multimodal multi-objective optimization problems

Abstract: In the multimodal multi-objective optimization problems (MMOPs), the distant solutions in the decision space have similar objective values, and these solutions with good diversity provide rich choices for decision makers. Traditional evolutionary algorithms have developed various diversity maintenance mechanisms to ensure the full search of decision space. However, these mechanisms do not make full use of the distribution and variation of PSs hidden in historical data, so their adaptive ability and environmental perception ability are poor. Inspired by data-driven evolutionary algorithms, it is a very promising research to use intelligent neural network models to learn knowledge hidden in historical data and assist evolutionary algorithms to explore PSs with different distributions. Therefore, this report will introduce the research of neural network-assisted evolutionary algorithm for solving MMOPs, including the shortcomings of traditional evolutionary algorithms for solving MMOPs, evolutionary algorithm design based on predictive neural network , and the help of graph learning to the evolution process.

The Speech title: Data-Driven Evolutionary Computation in Distributed Scenarios

Abstract: With the rapid development of distributed computing paradigms such as crowdsourcing, edge computing, et al., more data are collected and processed in a distributed manner. Due to the transmission cost or data privacy, these data cannot be fused and new challenges such as partial information, non-i.i.d. data and environmental-aware noises. To solve these problems, we study data-driven evolutionary computation in distributed scenarios. Firstly, data-driven evolutionary framework for distributed optimization is studied under partial information. Secondly, consistent learning strategy is proposed for non-i.i.d. data. Finally, the cooperative coevolutionary algorithm is developed to alleviate the influence of environmental-aware noises. Experimental results show that the proposed methods have satisfactory performance for data-driven distributed optimization.

The Speech title: Data-driven Learnable Evolutionary Algorithms for Complex Multiobjective Optimization

Abstract: Evolutionary algorithms are effective for solving complex optimization problems, especially those involving multiple objectives. However, their significant computational demands and inherent stochasticity can slow down convergence to global optima, particularly in intricate scenarios. In this talk, I will discuss our efforts in accelerating complex multiobjective optimization through data-driven learnable evolutionary generators. We train a model on elaborately prepared dataset to learn how to improve solutions in various optimization contexts, including large-scale, dynamic, constrained, and expensive multiobjective optimization problems. By studying how solutions improve from suboptimal to superior, the model learns important insights into performance improvements. We then create learnable evolutionary generators based on these insights. These generators produce higher-quality offspring solutions by concurrently exploring the learned representation spaces. This approach accelerates the population’s convergence toward global optimality, steering the search process in more promising directions and enhancing overall efficiency.

The Speech title: Expensive Optimization via Relation

Abstract: Expensive optimization problems pose significant challenges to traditional gradient-free optimization methods due to their high evaluation costs. Surrogate-assisted evolutionary algorithms (SAEAs) effectively address these challenges by using surrogate models to replace expensive evaluation functions. Designing an efficient surrogate model is crucial to the success of these algorithms. In recent years, constructing surrogate models based on the relationships between solutions has emerged as a novel modeling approach, following regression and classification models. This report proposes a general and comprehensive relational model framework and details specific implementation strategies.

The Speech title: Research on Cooperative coevolution for Large Scale Optimization

Abstract: In the era of data and intelligence, a large number of optimization problems abound in the practice of social production and life. Such problems often have complex characteristics, such as non-convex, multimodal, non-frivolous, etc., and it is even difficult to establish an accurate mathematical model. Evolutionary algorithms are widely used to solve complex optimization problems because of their swarm search characteristics. However, the proliferation of problem dimensions poses a serious challenge to the scalability of evolutionary algorithms. This report firstly introduces the cooperative coevolutionary algorithms for solving large-scale optimization problems based on the idea of divide-and-conquer, and then presents my research progress for constrained and unconstrained large-scale optimization problems.
