Shengcai Liu(刘晟材)
Short Biography
I received my B.Sc. and Ph.D. degrees in the School of Computer Science and Technology from the University of Science and Technology of China (USTC) in 2014 and 2020, respectively, under the supervision of Prof. Xin Yao and Prof. Ke Tang.
From Jan 2021 to Jan 2023, I was a Research Assistant Professor at the Department of Computer Science and Engineering (CSE), Southern University of Science and Technology (SUSTech).
I am also a member of the Nature Inspired Computation and Applications Laboratory (NICAL) led by Prof. Xin Yao and Prof. Ke Tang.
From Jan 2023 to May 2023, I was a Visting Professor at the Institute of High Performance Computing (IHPC), A*STAR, Singapore. Currently I am a research scientist at CFAR. I am in collaboration with Prof. Yew-Soon Ong from Nanyang Technological University (NTU).
Research Interest
Ultimately, I am obsessed with the theoretical foundations and practical approaches for the fully-automated design of general-purpose optimization algorithms.
Now I am working on:
Algorithm design by Evolutionary Computation, i.e., Algorithm Evolution
Deep learning to algorithm design, i.e., Learn to Optimize
Applications of these methods to practical combinatorial optimization problems such as evaluation of the robustness/safety of AI models (such as large language models), complex vehicle routing, influence blocking maximization, and 5G network end-to-end configuration
