Smith) mixes in time O*(n(2)R(2)/r(2)), where R and r are the radii of the inscribed and circumscribed balls of K. Thus after appropriate preprocessing, hit-and-run produces an approximately uniformly distributed sample point in time O*(n(3)), which matches the best known bound for other sampling algorithms. We show that the bound is best possible in terms of R, r and n. LA - English DB - MTMT ER - TY - JOUR AU - Solymosi, Tamás AU - Dombi, József TI - A method for determining the weights of criteria.
