Can pyperplan plan with domains that use metrics ?

[jorgerando]

Hello, I'm trying to make plans for domains that use PDDL fluents like this :

(define (domain tequila)

(:requirements :typing :fluents)

(:types bottle )

(:functions
(amount ?b - bottle)
)
(:predicates
(bottle-finished ?b - bottle)
)

(:action drink
:parameters (?b - bottle)
:precondition (>= (amount ?b) 1)
:effect (decrease (amount ?b) 1)
)
(:action done-drinking
:parameters (?b - bottle)
:precondition (= (amount ?b) 0)
:effect (bottle-finished ?b)
)
)

Can pyperplan plan on these types of domains ?

No, this is "numerical planning" and goes beyond the "classical planning" fragment that Pyperplan supports.

Hello, thank you very much for the information

I don't know if the question is a bit stupid, excuse my ignorance

Do you know of any numerical planner that allows you to implement custom heuristics like in Pyperplan ?

I don't, but perhaps others that are following this do? If not, a good place to ask this question is the "planning community" slack server. It is linked from here: http://planning.domains/about

I know that https://sites.google.com/view/enhsp/ supports heuristics, but it's not implemented in Python. I'd also recommend the slack server.

Hi, I don’t know if absolutely need Python, but check the ENHSP planner: https://gitlab.com/enricos83/ENHSP-Public <https://gitlab.com/enricos83/ENHSP-Public> Best wishes, -- Felipe Meneguzzi ***@***.***
