We develop the theory of regular cost functions over finite trees: a quantitative extension to the notion of regular languages of trees: Cost functions map each input (tree) to a v...
Reasoning about string variables, in particular program inputs, is an important aspect of many program analyses and testing frameworks. Program inputs invariably arrive as strings...
The use of genetic programming for probabilistic pattern matching is investigated. A stochastic regular expression language is used. The language features a statistically sound sem...
Abstract. A new class of languages of infinite words is introduced, called the maxregular languages, extending the class of ω-regular languages. The class has two equivalent desc...
We investigate the decidability of observational equivalence and approximation in “Syntactic Control of Interference” (SCI). By asg denotations of terms in an inequationally fu...
