class RegressionRuleApplicationExpression

Bases: object

An abstract regression rule grounding. For example, in (regression-ontop ?x ?y) where ?x and ?y are variables in the context.

Methods

ground(executor)	Ground the regression rule statement.
pddl_str()

Attributes

name	The name of the regression rule.
regression_rule	The regression rule that is applied.
arguments	The arguments of the regression rule.
maintains	The maintain expressions of the regression rule.
serializability	The serializability of the regression rule.
csp_serializability	The continuous serializability of the regression rule.

__init__(regression_rule, arguments, maintains=None, serializability='strong', csp_serializability='none')

Parameters:

• regression_rule (RegressionRule)

• arguments (Sequence[VariableExpression | UnnamedPlaceholder | ValueOutputExpression])

• maintains (Sequence[ValueOutputExpression] | None)

• serializability (SubgoalSerializability | str)

• csp_serializability (SubgoalCSPSerializability | str)
