We present an algorithm for Tchakaloff-like compression of quasi-Monte Carlo volume and surface integration on an arbitrary union of balls, via non-negative least squares. We also provide the corresponding Matlab codes together with several numerical tests.

Abstract
We present an algorithm for Tchakaloff-like compression of quasi-Monte Carlo volume and surface integration on an arbitrary union of balls, via non-negative least squares. We also provide the corresponding Matlab codes together with several numerical tests.
