Doering, Andreas C.2017-06-292017-06-292015One of the most basic operations, transforming a relationship into a function that gives the number of fulfilling elements, does not seem to be widely investigated. In this article a new algorithm for this problem is proposed. This algorithm can be implemented using Binary Decision Diagrams. The algorithm transforms a relation given as symbolic expression into a symbolic function, which can be further used, e.g. for finding maxima. The performance of an implementation based on JINC is given for a scalable example problem.enText/Journal Article0177-0454
