Optimal strategies to track and capture a predictable target
— We present an O(n log1+ε n)-time algorithm for computing the optimal robot motion that maintains lineof-sight visibility between a target moving inside a polygon with n vertic...

Optimal and Suboptimal Power Allocation Schemes for OFDM-based Cognitive Radio Systems
In this paper, we investigate an optimal power loading algorithm for an OFDM-based cognitive radio (CR) system. The downlink transmission capacity of the CR user is thereby maximiz...
