PDDL forall effect with durative actions

由 风格不统一 提交于 2020-08-09 07:36:47
问题 I am both using durative actions and trying to be able to clear a predicate over all elements of a certain type. See below. Is this possible? If so, does anyone know the correct syntax? Thanks! (:durative-action init :parameters (?r - robot) :duration ( = ?duration 1) :condition (and (at start (robot_uninitialized ?r)) (at start (robot_free ?r)) ) :effect (and (at start(not(robot_free ?r))) (at end (assign (robot_on_fastener_number_in_sequence) 1)) (at end (not(robot_uninitialized ?r))) (at

How to implement `forall` (mathematics) in a procedural or OO language

由 不羁岁月 提交于 2020-01-02 12:16:12
问题 I am trying to understand how to implement forall in a procedural or OO language like Ruby or JavaScript. For example (this is Coq): Axiom point : Type. Axiom line : Type. Axiom lies_in : point -> line -> Prop. Axiom ax : forall (p1 p2 : point), p1 <> p2 -> exists! l : line, lies_in p1 l /\ lies_in p2 l. My attempt at doing this is just defining a class such as this (call MainAxiom == ax ). class MainAxiom attr :p1 attr :p2 def initialize raise 'Invalid' if @p1 == @p2 l = Line.new check_lies

Coq convert non exist to forall statement

由 岁酱吖の 提交于 2019-12-02 15:59:10
问题 I'm new to Coq. Here's my problem. I have a statement says: H : forall x : term, ~ (exists y : term, P x y /\ ~ P y x) I guess it is equivalent to: forall x y : term, (P x y /\ ~ P y x) -> false But which tactic can I use to convert the hypothesis? 回答1: I don't know of a tactic to turn not-exists into forall-not, but you can always just assert and prove it. (If you need that repeatedly, you can pack that up into an Ltac tactic definition or a simple theorem[1].) Here's three ways of getting
