Niching for Population-Based Ant Colony Optimization
Most Ant Colony Optimization (ACO) algorithms are able to find a single (or few) optimal, or near-optimal, solutions to difficult (NP-hard) problems. An issue though is that a s...

Non-Regenerative Multicarrier MIMO Relay Communications Based on Minimization of Mean-Squared Error
Abstract—In this paper we propose non-regenerative multicarrier multiple-input multiple-output (MIMO) relay techniques that minimize the mean-squared error (MSE) of the signal wa...
