Towards Optimal Use of Multi-Precision Arithmetic: A Remark
If standard-precision computations do not lead to the desired accuracy, then it is reasonable to increase precision until we reach this accuracy. What is the optimal way of increa...

On Optimal Multiresolution Source-Channel Coding across Degraded Broadcast Channels
Inspired by a converse result, the concept of "probabilistically matched" sources and channels is extended to sources subject to multiresolution coding and degraded broa...
