A polynomially solvable case of unconstrained (-1,1)-quadratic fractional optimization

Meijia Yang, Yong Xia

In this paper, we consider an unconstrained (-1,1)-quadratic fractional optimization in the following form: $min_{x \in {- 1, 1}^{n}} (x^{T} A x + α) / (x^{T} B x + β)$ , where $A$ and $B$ , given by…

Closing the duality gap of the generalized trace ratio problem

Meijia Yang, Yong Xia

The generalized trace ratio problem {\rm (GTRP)} is to maximize a quadratic fractional objective function in trace formulation over the Stiefel manifold. In this paper, based on a…
