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...

Using Quaternions for Parametrizing 3-D Rotations in Unconstrained Nonlinear Optimization
In this paper we address the problem of using quaternions in unconstrained nonlinear optimization of 3-D rotations. Quaternions representing rotations have four elements but only ...

Measure Selection: Notions of Rationality and Representation Independence
We take another look at the general problem of selecting a preferred probability measure among those that comply with some given constraints. The dominant role that entropy maximi...
