IGRAPH -- Intermediate Goal Recognition with A Planning Heuristic

A tool for performing goal recognition using domain independent heuristics. Also known as AUTOGRAPH in a previous incarnation. See "A New Heuristic-Based model of Goal Recognition Without Libraries" by David Pattison, 2015.

Oct 2018

This is the code as it was post-corrections. It is untested in its current form, but it should still work (although a lot of the additional fluff for running experiments has been removed from Git... so let me know if it fails).

Usage

This code requires that JavaFF 2.1 (https://github.com/dpattiso/javaff), JavaSAS (https://github.com/dpattiso/javasasplus) and PlanThreader (https://github.com/dpattiso/planthreader) all be on the classpath, along with the contents of the /lib directory.

Note that IGRAPH uses a specific build (circa 2011?) of Helmert's SAS+ translation scripts which disables reachability analysis, so this cannot be swapped out for a more recent version.

More detailed usage is in doc/README.

Citation

The PhD thesis contains the most complete and representitive picture of this code, so it should probably be the thing to cite.
