Distributed Multi-Cell Zero-Forcing Beamforming in Cellular Downlink Channels
Abstract— For a multiple-input single-output (MISO) downlink channel with ¢ transmit antennas, it has been recently proved that zero-forcing beamforming (ZFBF) to a subset of (a...

General variable neighborhood search for the continuous optimization
We suggest a new heuristic for solving unconstrained continuous optimization problems. It is based on a generalized version of the variable neighborhood search metaheuristic. Diff...
