Taking a scheme based on the notion of extremal aiming strategies of N. N. Krasovski, the present paper concentrates on constructive solutions generated through ellipsoidal-valued calculus and related approximation techniques for set-valued maps. Namely, the primary problem which originally requires an application of set-valued analysis is substituted by one which is based on ellipsoidal-valued functions. This yields constructive schemes applicable to algorithmic procedures and simulation with computer graphics.</mods:abstract><mods:originInfo><mods:dateIssued encoding="iso8601">1991</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Birkhäuser Boston</mods:publisher></mods:originInfo><mods:genre>Book Section</mods:genre></mods:mods>
