  abstract =     "Model learning often implies exploring a vast search
                 space of possible hypotheses in the hope of finding a
                 solution. Qualitative model learners are mostly based
                 on Inductive Logic Programming (ILP), which is a
                 systematic method which tends to be well fitted for
                 exploring solutions in a narrow search space. We
                 present a semi-quantitative model learner that uses
                 Genetic Programming (GP), which is well suited for
                 exploring a broad search space. We learn simple
                 physical systems based on a formalism involving both
                 crisp numbers and fuzzy quantity spaces. We use the ECJ
                 framework,1 and the fitness of a model is set to be
                 optimal when it covers all positive examples. Several
                 experiments are performed to learn and reuse models of
                 physical systems of increasing complexity; firstly a
                 u-tube, then coupled tanks, and finally cascading
                 tanks. Results show that the system can approximate the
                 target models in reasonably good conditions, and that
                 there is still scope for optimisation.",
