Abstract :
Abstract. In this paper, we study the problem of minimizing the ra-
tio of two quadratic functions subject to a quadratic constraint. First
we introduce a parametric equivalent of the problem. Then a bisection
and a generalized Newton-based method algorithms are presented to solve
it. In order to solve the quadratically constrained quadratic minimization
problem within both algorithms, a semidefinite optimization relaxation ap-
proach is presented. Finally, two set of examples are presented to compare
the performance of algorithms.
