En fait, Metagolf entier


17

Contexte

En fait (le successeur de Sérieusement ) est un langage de golf impératif basé sur la pile que j'ai créé en novembre 2015. Comme beaucoup d'autres langues de golf, il a des commandes à un octet qui exécutent différentes fonctions en fonction du contenu de la pile. L'une de ses spécialités est les mathématiques - il a une grande variété de commandes basées sur les mathématiques. Cependant, pour effectuer des opérations mathématiques, vous devez mettre (un ou plusieurs) nombres sur la pile. Pousser une valeur spécifique dans le moins d'octets possible est délicat, car il existe de nombreuses options différentes. Dans ce défi, vous ferez exactement cela: représenter des nombres (en particulier des entiers) en fait en aussi peu d'octets que possible.

Le défi

Étant donné un entier Nen entrée, un code de sortie valide valide qui se traduit par Nêtre poussé vers la pile.

  • L'entrée sera dans la plage d'un entier complément à deux signé 32 bits (c'est-à-dire les entiers dans la plage inclusive [-2147483648, 2147483647]).
  • Le résultat doit être un entier (pas un flottant, une chaîne, une liste ou une fonction) et doit être au-dessus de la pile.
  • Vous ne pouvez pas faire d'hypothèses sur le contenu de la pile (comme si elle est vide ou non). Aucune valeur existante sur la pile ne doit être modifiée ou réorganisée.
  • Le dernier commit de Actually au moment où j'écris ce défi doit être utilisé. Si je fais des corrections de bugs ou des améliorations de performances (ou toute autre modification mineure qui ne supprime pas ou ne modifie pas la fonctionnalité des commandes autorisées), je mettrai à jour cette version.
  • Votre solution doit faire au moins aussi bien que la solution triviale (ajouter :à l'entrée pour faire un littéral numérique).
  • Votre score sera la somme des longueurs des solutions triviales moins la somme des longueurs des sorties pour la sélection de 1000 entiers de complément à deux signés 32 bits utilisés pour la notation, qui peuvent être trouvés ci-dessous. Je me réserve le droit de modifier les entiers de notation à tout moment, s'il y a un besoin (comme l'optimisation pour les cas de test ou les cas de test qui ne sont pas suffisamment approfondis).
  • Les solutions doivent générer une réponse valide dans les 30 secondes pour chaque entrée. Le chronométrage sera effectué sur un espace de travail Cloud9 gratuit standard .

Commandes

Par souci de simplicité, seules 141 des 208 commandes (actuellement) peuvent être utilisées, et de nombreuses surcharges de ces 141 qui ne sont pas liées à la compression des nombres ont été supprimées.

Voici un programme Python 3 qui peut être utilisé pour vérifier et noter une soumission:

#!/usr/bin/env python3

import shlex
import os
import sys
import subprocess

try:
    from seriously import Seriously
except:
    print("Unable to load Seriously. Run 'pip3 install seriously' to install it.")
    exit()

if len(sys.argv) < 2:
    print("Usage: python3 {} 'command_to_call_your_program'".format(sys.argv[0]))
    exit()

sys.stdin = open(os.devnull, 'r')

with open('nums.txt') as f:
    nums = [int(x) for x in f]

total = 0

for num in nums:
    p = subprocess.Popen(shlex.split(sys.argv[1]), stdin=subprocess.PIPE, stdout=subprocess.PIPE, universal_newlines=True)
    try:
        out = p.communicate(str(num), timeout=30)[0].strip()
    except subprocess.TimeoutExpired:
        print("Program failed to finish within 30 seconds for {}".format(num))
        exit()
    val = Seriously().eval(out)[0]
    if not len(out) <= len(':'+str(num)):
        print("Failed to do at least as well as naive on {} ({})".format(num, out))
        exit()
    elif val != num or not isinstance(val, int):
        print("Incorrect output: {} instead of {}".format(val, num))
        exit()
    else:
        print("{}: {} ({})".format(num, out, len(out)))
        total += len(out)

print("Total:", total)

Pouvons-nous utiliser des données persistantes? (Comme pour stocker un tas de nombres premiers ou de nombres de Fibonacci)
Blue

"Votre solution doit faire mieux que la solution triviale, sauf si la solution triviale est optimale pour la valeur donnée." pour chaque entrée? donc si mon algorithme ne fait que mieux que la solution triviale 99% du temps, les 1% restants me disqualifient si l'un d'eux n'est pas optimal?
Sparr

@Blue C'est acceptable.

@Sparr Cela signifie que vous ne pouvez pas simplement sortir la solution triviale s'il existe une meilleure solution.

@ven C'est normal. Le nom de la langue est Sérieusement. Dans ce défi, nous traitons spécifiquement de Serious v2, qui est nommé Actually.

Python 3, 51 52 57 octets enregistrés

Cette brute de programme se fraye un chemin à travers un nombre important de programmes de 1 à 5 caractères, en utilisant un ensemble limité de 54 56 instructions et beaucoup d'élagage en fonction de l'état de la pile avant d'ajouter chaque nouvelle instruction. Cela prend environ une minute pour fonctionner sur mon ordinateur portable. 6 caractères prendraient des heures.

J'ai rapidement remarqué que vous utilisez ~ et je ne le suis pas, ce qui économise quelques octets. J'ai passé 30 minutes à comprendre pourquoi votre score pour les petits nombres était meilleur quand j'en trouve une poignée que vous n'avez pas. J'ai finalement réalisé que je comptais le cas trivial pour 0-9 comme 0-9, pas: 0-: 9. Me coûte 6 points sur les trois solutions. Merci de m'avoir fait enquêter là-dessus.

Cette solution fonctionne à l'envers des deux précédentes. Au lieu d'assembler des programmes de gauche à droite, je commence à la fin et je recule. Pour que cela fonctionne, je dois réellement exécuter mes programmes et je ne peux pas tailler les instructions en fonction de leurs paramètres car leurs paramètres n'existent pas encore lorsqu'ils sont ajoutés. Ma solution de contournement pour cela n'est pas présente dans cette réponse; cela implique de dire à SeriousCommands.py de lancer une IOError à chaque fois que les fonctions génératrices de folie sont appelées avec de gros arguments, et de lever cette exception pour que je puisse l'attraper.

Voici comment fonctionne ce programme:

Je commence avec une pile vide et je sais que je veux un seul numéro. Quelles instructions peuvent accomplir cela? 0-9 me donne un entier et ne nécessite rien sur la pile, donc ce sont des programmes complets. K, L, T, e et un tas d'autres m'obtiennent un nombre et ont besoin d'un nombre (je ne fais pas de différence entre les flottants et les entiers jusqu'à ce que la sortie soit vérifiée). *, +, etc. transformez deux nombres en un nombre. Etc.

Maintenant, j'ai quelques programmes complets et une liste de suffixes de programme incomplets qui peuvent transformer un arrangement connu de types sur la pile en un seul numéro que je veux. Répétez le processus et ajoutez à chacune d'entre elles toutes les instructions qui peuvent remplir une / certaines / toutes leurs exigences de pile, enregistrez celles qui sont des programmes complets et envoyez les incomplètes à l'étape suivante.

Au cours des deux dernières étapes, je taille beaucoup les possibilités car je sais que je ne peux plus avoir besoin de pile lorsque j'ai terminé (donc 0-9 sont les seules instructions valides à être ajoutées au programme en dernier) et avant cela Je ne peux avoir qu'un seul numéro comme exigence.

Sans surprise, cette solution produit exactement le même score que le meilleur de mes deux autres solutions. Ils trouvent presque exactement le même ensemble de résultats.

Ce programme peut probablement aller jusqu'à 6 caractères en moins de temps que l'autre, mais ce serait quand même prohibitif.

Je pense qu'une excellente solution pourrait être faite en combinant les deux, en assemblant les préfixes et les suffixes et en les joignant au milieu si leurs piles sont compatibles.

Python 3, 34 39 octets enregistrés

Ce programme calcule simplement tous les nombres qu'il peut atteindre en utilisant de simples combinaisons des opérateurs binaires et unaires, ce qui couvre 366k sur 4B entiers, pour un total de quelques dizaines de cas de test. Ensuite, je génère ces résultats ou la solution triviale. C'est techniquement contraire aux règles, car il est certain qu'il existe une meilleure solution pour certains cas, mais je suis convaincu que personne ne parviendra à trouver une solution qui réponde certainement à cette règle.

De plus, je ne fais que produire toutes les sorties à la fois, car 30 secondes de temps de configuration sont supportables une fois, pas 1000 fois. Les sections commentées augmentent considérablement la durée d'exécution tout en réduisant à peine le score.

@ Le score de KevinLau-notKenny dans ce défi est la taille totale de la sortie, le millier de programmes réellement, pas la taille du programme Python
Sparr

J'aime cette approche. Je suis prêt à être un peu plus flexible avec la restriction de temps et la règle du must-do-better-trivial si elle permet des solutions plus intéressantes - je voulais principalement éviter les solutions de force brute non testables qui fonctionnent pendant des siècles et une solution triviale de "prepend a:", qui est sans imagination et va à l'encontre de l'esprit du défi.
Mego

J'ai modifié les exigences pour que les solutions ne fassent qu'au moins aussi bien que la solution triviale, plutôt que meilleure si possible, et j'ai augmenté le délai à 30 secondes par entrée. Votre solution est maintenant valide et vous pourrez peut-être apporter des améliorations supplémentaires aux exigences assouplies.
