Abstract [eng] |
In this paper we consider applications of quadratic programming to solving some problems. First of all we define a quadratic programming problem as an optimization problem with a quadratic objective function and some constraints. We present two important properties of a quadratic programming problem: (i) quadratic programming problem with a convex and with integer number coefficients objective function and linear constraints in complexity class P and (ii) quadratic programming problem with nonconvex (concave or non convex, non concave) and with integer number coefficients objective function and linear constraints in complexity class NP-hard. Next we present results of research aimed at analysing some problems that can be formulated as quadratic programming problems: visualisation of multidimensional data, search for maximum clique of a graph, and classification of data. |
