Экстремальные эллипсоиды как аппроксиматоры пространства дизайна в задачах предсказательного метамоделирования

Чепыжов В. В., Бедринцев А., Чернова С.

This paper proposes an approach to obtaining of the set of admissible values of the optimization variables (design space) in the form of extreme ellipsoids describing a given set of points and inscribed in a given set of linear constraints. Considered ellipsoids include Principal Component’s ellipsoid, minimal volume ellipsoid and ellipsoid with minimal trace of its matrix containing given points. We have developed the procedures which change ellipsoid built based on points set exclusively in order to inscribe it into polyhedron. Ellipsoids are constructed by solving corresponding optimization problems which are formulated as convex programming problems using linear matrix inequalities.
