In this paper we consider the structural analysis problem for differential-algebraic systems with conditional equations. This consists, given a conditional differential algebraic ...
The Eulerian closed walk problem in a digraph is a well-known polynomial-time solvable problem. In this paper, we show that if we impose the feasible solutions to fulfill some pre...
This paper discusses four store-based concrete memory models. We characterize memory models by the class of pointers they support and whether they use numerical or symbolic offset...
In this paper, we present Aspic, an automatic polyhedral invariant generation tool for flowcharts programs. Aspic implements an improved Linear Relation Analysis on numeric counte...
A previously introduced combination of the bialgebraic approach to structural operational semantics with aic modal logic is re-examined and improved in some aspects. Firstly, a mo...
