Detecting structures in differential algebraic equations: Computational aspects

摘要

Differential algebraic equations (DAEs) are often automatically generated, in particular, by coupling different tools. These DAEs are unstructured in the sense that they do not reveal their mathematical structure a priori. In view of a reliable treatment of those DAEs, their mathematical structure should be uncovered and monitored also by computational methods. We discuss several computational aspects of the tractability index concept.
