Aries

Aries is a project aimed at exploring constraint-based techniques for automated planning and scheduling. It is currently under heavy development and generaly should not be considered stable or efficient (even thought some part are).

Building

Build relies on cargo can be triggered like so:

cargo build # debug non-optimized build
cargo build --release ## optimized build

This build compile artifacts and place them in the target/debug or target/release directory.

Library Modules

• sat: reimplementation of the minisat solver, with initial work for lazy SMT usage
• stn: algorithms for Simple Temporal Networks (aka Difference Logic) reasoning.
• planning: module for reasoning on temporal and hierachical planning problems in a chronicle based representation.

Executables

While aries is primarily thought as a library it does come with some programs to allow testing and demonstration. Those include:

• gg: a state-space planner for PDDL based on heuristic search with the hadd heuristic.
• minisat: sat solver that mimic the minisat solver
• jobshop: lazy-SMT based solver for the jobshop problem
• pddl2chronicles: a tool to convert PDDL into a JSON representation of chronicles

Source code of these executables can be found in the directory apps/src/bin. One can install an executable locally like so (example for gg):

cargo install --bin gg --path . # should be done in the "apps/" sub-crate
