MixR is a framework for integrating multiple sentential and diagrammatic theorem provers, as well as informal tools from arbitrary domains (such as image processing, natural language processing, amongst others) into one heterogeneous reasoning system.
This project is related to (but not dependent on) Speedith (a diagrammatic theorem prover for spider diagrams).
Speedith and Isabelle (through I3P) are the first supported theorem provers to be integrated into the MixR framework--resulting in the Diabelli Heterogeneous Reasoning System. With Diabelli it is possible to use spider diagrams while performing proofs in Isabelle. Isabelle formulae are automatically translated to spider diagrams if possible. The user can then reason on the spider diagram and then return the result of reasoning with the spider-diagrammatic representation back to Isabelle.
We provide two further examples of heterogeneous reasoning with MixR:
- NatLang: demonstrates how reasoning with natural languages can be performed in a general-purpose sentential and formal theorem prover (in this case, Isabelle).
- PicProc: demonstrates how one can reason about bitmap images within Isabelle.
Both of the examples above use the novel concept of placeholders to insert natural language sentences and images into Isabelle's formulae.

This is enough just to build the MixR framework (without any plugins!). This means that none of the examples (Isabelle, Speedith, NatLang, PicProc, and TPTP will work).
To build MixR framework (MixR core), open the
devel/MixRFrameworkproject in NetBeans.
To build Diabelli (with Isabelle, Speedith, NatLang, PicProc, and TPTP support), proceed as follows:
Download and unpack Isabelle 2012 into the
~/bin/Isabelle2012folder. Isabelle 2012 can be downloaded from:
On Mac Isabelle might need Java 6. You can get it from here: http://www.oracle.com/technetwork/java/javase/archive-139210.html

Clone the Speedith and iCircles repositories (follow their installation instructions from README.md):
git clone https://github.com/urbas/speedith.git git clone https://github.com/urbas/iCircles.git
iCirclesfolders must be siblings to the
