Core Competency:

Our major research interest lies in the construction of systems for handling incomplete, inconsistent or evolutionary information that allow for qualitative modelling of complex systems. We apply these systems in the context of bioinformatics, among others, for modelling and advanced simulation of biological networks.

Contribution to Work Programme:

WP1: Causal languages allow for expressing high-level specifications designed for representing dynamical systems. Two salient features of this approach are its declarativeness and succinctness, making it highly elaboration tolerant. A causal specification can be used for various purposes, among them, prediction and simulation, explanation and diagnosis, planning of experiments, etc. The idea is to express a biological network in a causal language that is subsequently treated with model based automatic problem solvers, like SAT- or ASP-solvers (being highly optimised and allowing for treating state spaces of over one million variables). The major contribution of this partner will be to WP1.
