The authors are interested in asymptotic results on tha approximation orders of general convex bodies by random polytopes. Let \(K\) be a convex body in \(\mathbb{R}^d\), \(X=(x_1,\ldots,x_n)\) a random sample of \(n\) independent points in \(K\), \(K_n\) the convex hull of \(X_n\) and \(W(\cdot)\) the mean width. The authors generalize the asymptotic formula for the expectation \(W(K)-W(K_n)\) and the strong law of large numbers for \(W(K_n)\), which were earlier known, when \(\partial K\) has positive Gaussian curvature.
