A central goal of algorithmic research is to determine how fast computational problems can be solved in the worst case. Unfortunately, for many central problems, the best known running times are essentially those of their classical algorithms from the 1950s and 1960s. For years, the main tool for explaining computational difficulty have been NP-hardness reductions, basing hardness on P\neq NP. However, if one cares about exact running time (as opposed to merely polynomial vs non-polynomial), NP-hardness is not applicable, especially if the problem is already solvable in polynomial time. In recent years, a new theory has been developed, based on ``fine-grained reductions'' that focus on exact running times. In this talk I will give an overview of the current progress in this area, and will highlight some exciting new developments.



Virginia Vassilevska Williams is the Steven and Renee Finn Career Development Associate Professor at MIT CSAIL. She obtained her Ph.D. from Carnegie Mellon University in 2008. After research and postdoctoral positions at the IAS in Princeton, UC Berkeley and Stanford, she spent 3.5 years as an assistant professor at Stanford University before joining MIT in early 2017. She is the recipient of an NSF CAREER award, a Google Faculty Research Award and an Alfred P. Sloan Research Fellowship, and in 2018 gave an invited lecture at the International Congress of Mathematicians.


This Distinguished Lecture is part of the Illinois Computer Science Speaker Series.
