class GStripsProblem[source]#

Bases: object

A grounded STRIPS task. It is composed of three parts:

The current state, which is a set of propositions.
The goal state, which is a grounded STRIPS classifier.
The operators, which is a list of applicable grounded STRIPS operators.

Methods

compile()

Compile all operators and derived predicates.

Attributes

`facts`	The relevant facts in the task.
`state`	The initial state.
`goal`	The goal expression.
`operators`	The list of operators.
`regression_rules`	The list of regression rules.
`derived_predicates`	The list of derived predicates.
`is_relaxed`	Whether the task is a delete-relaxed task.
`goal_implicit_propositions`	The implicit propositions in the goal.

__init__(state, goal, operators, is_relaxed=False, goal_implicit_propositions=None, regression_rules=None, derived_predicates=None, facts=None)[source]#
