On the Influence of the Variable Ordering for Algorithmic Learning using OBDDs

OBDDs with a fixed variable ordering are used successfully as data structure OBDDvariable ordering. There are functions with the following properties. They have OBDDs of linear size for optimal variable orderin...

On Random Orderings of Variables for Parity Ordered Binary decision Diagrams.

It is proved that for every Boolean function, the expected size of its representation using Parity OBDD with a random ordering of the variables and the size of such a representation for the worst ordering are polynomialy re...

Chromatic aberrations of thin refractive variable-focus lens

The paper presents an approach to an analysis of the third order chromatic aberrations of thin refractive fluid lenses with a variable focal length. Formulas were derived for the change of the third-order aberration coeffic...

Weighted First-Order Model Counting in the Two-Variable Fragment With Counting Quantifiers

It is known due to the work of Van den Broeck, Meert and Darwiche that weighted first-order model counting (WFOMC) in the two-variable fragment of first-order logic can be solved in time polynomial in the number of domain e...

Low-order Hamiltonian operators having momentum

We describe all fifth-order Hamiltonian operators in one dependent and one independent variable that possess momentum, i.e., for which there exists a Hamiltonian associated with translation in the independent variable. Simi...
