Attacking Decipherment Problems Optimally with Low-Order N-gram Models
We introduce a method for solving substitution ciphers using low-order letter n-gram models. This method enforces global constraints using integer programming, and it guarantees t...

Complexity Constrained Noise-Free CDMA: Optimal Power Distribution and Spectral Efficiency
The issue of multiuser cooperation in a complexity constrained noise-free CDMA channel is addressed. Multiuser cooperation is imperative if conventional demodulation is expected to...

Constrained Subspace ICA Based on Mutual Information Optimization Directly
We introduce a new approach to constrained Independent Component Analysis (ICA) by formulating the original, unconstrained ICA problem as well as the constraints in mutual informa...

Mean-Variance Optimization in Markov Decision Processes
We consider finite horizon Markov decision processes under performance measures that involve both the mean and the variance of the cumulative reward. We show that either randomiz...

Computing Optimal Coverability Costs in Priced Timed Petri Nets
—We consider timed Petri nets, i.e., unbounded Petri nets where each token carries a real-valued clock. Transition arcs are labeled with time intervals, which specify constraints...
