Razor: Provenance and Exploration in Model-Finding

18 pagesPublished: July 5, 2015


Razor is a model-finder for first-order theories presented
geometric form; geometric logic is a variant of first-order logic
that focuses on ``observable'' properties. An important guiding
principle of Razor is that it be accessible to users who are
not necessarily expert in formal methods; application areas
include software design, analysis of security protocols and
policies, and configuration management.

A core functionality of the tool is that it supports
exploration of the space of models of a given input theory,
as well as presentation of provenance information about the
elements and facts of a model. The crucial mathematical tool is
the ordering relation on models determined by homomorphism, and
Razor prefers models that are minimal with respect to this

Keyphrases: geometric logic, model finding, Provenance
