Box-constrained vector optimization: a steepest descent method without “a priori” scalarization [PDF]
In this paper a notion of descent direction for a vector function defined on a box is introduced. This concept is based on an appropriate convex combination of the “projected” gradients of the components of the objective functions.

A New Gap Function for Vector Variational Inequalities with an Application
Journal of Applied Mathematics, 2013 We consider a vector variational inequality in a finite-dimensional space. A new gap function is proposed, and an equivalent optimization problem for the vector variational inequality is also provided.

Multiobjective Lagrangian duality for portfolio optimization with risk measures [PDF]
In this paper we present an application for a multiobjective optimization problem. The objective functions of the primal problem are the risk and the expected pain associated to a portfolio vector. Then, we present a Lagrangian dual problem for it.

Generalised vector precoding design based on the MBER criterion for multiuser transmission
, 2010 A generalised vector precoding (VP) design based on the minimum bit error rate (MBER) criterion is proposed for multiuser transmission in the downlink of a multiuser system where the base station (BS) equipped with multiple transmit antennas communicates

Increase-along-rays property for vector functions [PDF]
In this paper we extend to the vector case the notion of increasing along rays function. The proposed definition is given by means of a nonlinear scalarization through the so-called oriented distance function from a point to a set.

A heuristic fault based optimization approach to reduce test vectors count in VLSI testing
Journal of King Saud University: Computer and Information Sciences, 2019 In this work we have proposed a heuristic approach to reduce the test vector count during VLSI testing of standard ISCAS circuits. With the shrinking die-space and increasing circuitry on a single Integrated circuit, the number of test vectors required ...
