ACL2 Seminar, 2/27/2018 Speaker: Judy Altoyan Title: UML Class Diagram Equivalence Abstract: Given two UML class diagrams (a.k.a. MDE metamodels) that are syntactically different, can we prove that they are semantically equivalent? We are looking for formalisms to help us precisely define and solve this problem, along with a suitable tool to assist in proving (or disproving) their equivalence.
