We consider the problem of separating two sets of points in an n-dimensional real space with a (hyper)plane that minimizes the sum of <i>L</i>₂-n...

Assouad has shown that a real-valued distance <i>d</i> = (<i>d</i>_<i>ij</i>) _{1 &le; <i>i</i> &lt; <i>j</i> &le; <i>n</i>} is isome...

This paper answers a query of S. Vincze (Acta Univ. Szeged, Sect. Sci. Math. 12 A (1950) 136-142): find the convex octagon with unit-length sides and minim...

Treatment of imprecise probabilities within the probabilistic satisfiability approach to uncertainty in knowledge-based systems is surveyed and discussed. ...
