Optimal scaling of a gradient method for distributed resource allocation
Distributed optimization resource allocations weighted gradient methods convergence rates semidefinite programming
2015/8/10
We consider a class of weighted gradient methods for distributed resource allocation over a network. Each node of the network is associated with a local variable and a convex cost function; the sum of...
An interior-point method for large-scale network utility maximization
Newton the interior point networks concave utility functions disperse method dual decomposition algorithm
2015/8/10
We describe a specialized truncated Newton primal-dual interior-point method that solves large scale network utility maximization problems, with concave utility functions, efficiently and reliably. Ou...
A tractable method for robust downlink beamforming in wireless communications
Wireless communication system sound localization noise signal interference ratio
2015/8/10
In downlink beamforming in a multiple-input multiple-output (MIMO) wireless communication system, we design beamformers that minimize the power subject to guaranteeing given signal-to-interference noi...
