Hamiltonian index is NP-complete
In this paper we show that the problem to decide whether the hamiltonian index of a given graph is less or equal to a given constant is ∗ Research supported by grants No. 1M0545...

A comparison of semantic models for noninterference
The literature on definitions of security based on causality-like notions such as noninterference has used several distinct semantic models for systems. Early work was based on st...

Resource allocation with time intervals
We study a resource allocation problem where jobs have the following characteristics: Each job consumes some quantity of a bounded resource during a certain time interval and indu...

Weak bisimulation for Probabilistic Timed Automata
We are interested in describing timed systems that exhibit probabilistic behaviour. To this purpose, we consider a model of Probabilistic Timed Automata and introduce a concept of ...

Monad transformers as monoid transformers
The incremental approach to modular monadic semantics constructs complex monads by using monad transformers to add computational features to a preexisting monad. A complication of...

Parametric random generation of deterministic tree automata
Uniform random generators deliver a simple empirical means to estimate the average complexity of an algorithm. We present a general rejection algorithm that generates sequential l...

Analysis of a cellular automaton model for car traffic with a slow-to-stop rule
We propose a modification of the widely known Benjamin-Johnson-Hui (BJH) cellular automaton model for single-lane traffic simulation. In particular, our model includes a `slow-to-...
