Mapping Problems with Finite-Domain Variables into Problems with Boolean Variables
We define a collection of mappings that transform many-valued clausal forms into satisfiability equivalent Boolean clausal forms, analyze their complexity and evaluate them empir...

A Fast State Reduction Algorithm for Incompletely Specified Finite State Machines
Abstract-- This paper proposes a state reduction algorithm for incompletely specified FSMs. The algorithm is based on iterative improvements. When the number of compatibles is like...

Finite State Transducers Approximating Hidden Markov Models
This paper describes the conversion of a Hidden Markov Model into a sequential transducer that closely approximates the behavior of the stochastic model. This transformation is es...

An Optimal Construction of Finite Automata from Regular Expressions
We consider the construction of finite automata from their corresponding regular expressions by a series of digraph-transformations along the expression’s structure. Each interm...

Computationally and Algebraically Complex Finite Algebra Membership Problems
In this paper we produce a finite algebra which generates a variety with a PSPACE-complete membership problem. We produce another finite algebra with a γ function that grows exp...
