What are the best planners for PDDL2.1?

Question

I am working now on my internship with PDDL: I am struggling to find the appropriate planners for PDDL2.1. The task is to compare different PDDL planners according to the following criterias:

1. version of PDDL.

2. Benchmark.

3. supporting the numeric values.

4. implmented language for each planner.

5. API.

My question is:

What are the "two" planners to choose according to the description to compare between them in order to make sense?

Thanks

Answer 1

Sounds like a fun internship! You can pick through these resources*:

• Documented list of planners
• Package to run many of them in a docker container (docker image) (list of planners currently supported)

OPTIC, ENHSP (3 versions), and SMTPlan would be a good start for 2.1. G'luck!

Answer 2

I am a student working on my master thesis, actively using PDDL 2.1.

The latest planning framework for robotics like 'ROS2_Planning_System' (Plansys2) used POPF and TFD planners. These planners can be used in your work. In my opinion, the POPF planner (recent version or update POPF+) is quite suitable for numeric fluents.

I hope this is helpful to you and All the best for your work!
