EURASIP Journal on Advances in Signal Processing, 2010 The problem of jointly optimizing the source precoder, relay transceiver, and destination equalizer has been considered in this paper for a multiple-input-multiple-output (MIMO) amplify-and-forward (AF) relay channel, where the channel estimates of all ...

Impact of endogenous learning curves on maritime transition pathways
Environmental Research LettersThe maritime industry is a crucial hard-to-abate sector that is expected to depend on high-energy density renewable liquid fuels in the future. Traditionally, decarbonization pathways have been assessed assuming exogenous cost trajectories for renewable ...

A class of nonconvex semidefinite programming in which every KKT point is globally optimal
We consider a special class of nonconvex semidefinite programming problems and show that every point satisfying the Karush--Kuhn--Tucker (KKT) conditions is globally optimal despite nonconvexity. This property is related to pseudoconvex optimization and fractional programming.

A novel approach to Bilevel nonlinear programming
, 2007 Recently developed methods of monotonic optimization have been applied successfully for studying a wide class of nonconvex optimization problems, that includes, among others, generalized polynomial programming, generalized multiplicative and fractional ...

Industrial & Engineering Chemistry ResearchNonconvex quadratically constrained programs (QCPs) with bilinear terms frequently arise in the optimization of chemical process systems such as water-using networks (WUNs). While global optimization approaches based on spatial branch-and-bound and mixed-integer linear programming relaxations have achieved significant advances, they remain ...

Supporting weakly Pareto optimal allocations in infinite dimensional nonconvex economies [PDF]
In this paper, we prove a new version of the Second Welfare Theorem for economies with a finite number of agents and an infinite number of commodities, when the preference correspondences are not convex-valued and/or when the total production set is not ...

On Insurer Portfolio Optimization. An Underwriting Risk Model [PDF]
Multicriteria portfolio optimization started with the Markowitz mean-variance model (Markowitz 1952, 1959). This model assumes that the goal of an average or standard investor is to maximize the unknown return on investment.

Global optimization for nonconvex optimization problems [PDF]
, 2012 Duality is one of the most successful ideas in modern science [46] [91]. It is essential in natural phenomena, particularly, in physics and mathematics [39] [94] [96].
