Graphs are among the most well-studied objects in combinatorics and optimization, and are central to many areas of algorithm design. In this talk, I describe some powerful new tools critical to recent progress on fundamental problems in graph algorithms, including long-standing problems such as all-pairs minimum cut, parallel shortest paths, and dynamic connectivity. Specifically, I demonstrate how the interplay between structure, approximation, and iteration forms the basis of my research process, and discuss how these ideas can lead to further breakthroughs.
Bio: Jason Li is a Simons Institute postdoctoral fellow working on fundamental graph optimization problems such as minimum cut and maximum flow. His research efforts have led to state-of-the-art algorithms for a wide array of classic problems, including deterministic global minimum cut, minimum k-way cut, Gomory-Hu tree or all-pairs minimum cut, and single-source shortest paths in parallel.
He has received the EATCS Distinguished Dissertation Award, the Machtey Best Student Paper Award at FOCS 2019, and the Best Paper Award at ESA 2021.
