Convergence rates of moment-sum-of-squares hierarchies for volume approximation of semialgebraic sets

Original Paper


Moment-sum-of-squares hierarchies of semidefinite programs can be used to approximate the volume of a given compact basic semialgebraic set K. The idea consists of approximating from above the indicator function of K with a sequence of polynomials of increasing degree d, so that the integrals of these polynomials generate a convergence sequence of upper bounds on the volume of K. Under certain assumptions, we show that the asymptotic rate of this convergence is at least \(O(1{/}\log \log d)\) in general and \(O(1 / \log d)\) provided that the semialgebraic set is defined by a single inequality.

The authors would like to thank the three anonymous reviewers for their constructive comments that helped improve the manuscript as well as to J. Nie for pointing out that the complexity can be reduced if the semialgebraic set is defined by a single constraint. The research of M. Korda was supported by the Swiss National Science Foundation under Grant P2ELP2_165166.
