Highlighting Named Entities in?Input for?Auto-formulation of?Optimization Problemsccomplished by analytical software, formulating a problem as a set of mathematical operations has been typically done manually by domain experts. Recent machine learning methods have shown promise in converting textual problem descriptions to corresponding mathematical formulations. This paper prese

Formalizing Free Groups in?Isabelle/HOL: The Nielsen-Schreier Theorem and?the?Conjugacy Problemt result in the theory of free groups is the Nielsen-Schreier Theorem, which states that any subgroup of a free group is free. In this paper, we present a formalisation, in Isabelle/HOL, of a combinatorial proof of the Nielsen-Schreier theorem. In particular, our formalisation applies to arbitrary s

Morphism Equality in?Theory Graphs paths as the morphisms. But in contrast to generated categories, theory graphs do not allow for an equational theory on the morphisms. That blocks formalizing important aspects of theory graphs such as isomorphisms between theories..MMT is essentially a logic-independent language for theory graphs.
