SymbolicPlanners.jl

Symbolic planners for problems and domains specified in PDDL.

Installation

Make sure PDDL.jl is installed. Then run

add https://github.com/JuliaPlanners/SymbolicPlanners.jl

at the Julia package manager.

Features

  • Forward state-space planners (A*, BFS, etc.)
  • Backward (i.e. regression) planners
  • Relaxed-distance heuristics (Manhattan, hadd, hmax, etc.)

Planners

Heuristics

  • Goal Count: counts the number of unsatisfied goals
  • Manhattan: L1 distance for arbitrary numeric fluents
  • HSP heuristics: hadd, hmax, etc.
  • HSPr heuristics: the above, but for backward search
  • FF heuristic: length of a relaxed plan, used by the Fast-Forward planner
