Java, 330 Points
Avant de me faire ridiculiser pour un score aussi élevé, permettez-moi de préciser que j'ai tenté d'essayer de résoudre ce problème différemment, sachant qu'il ne serait probablement pas aussi optimal que certaines des meilleures réponses données ici. J'étais plus ou moins curieux de savoir si je pouvais obtenir près ce qui à ma grande surprise , je ne savais pas à quel point le pire cela tournerait. Voici le résumé de mon approche:
Développez un algo pour résoudre un puzzle de sudoku.
Développez un algorithme de brouillage qui peut encore être résolu. Il le fait un peu au hasard tout en éliminant les indices qui peuvent être trivialement déterminés au préalable. Je pouvais obtenir environ 22 indices de manière fiable avant que cela prenne beaucoup trop de temps.
Une fois brouillé, le puzzle pourrait être représenté par un triplet d’entiers à un chiffre pour chaque indice, dans mon cas, 22 triplets de 3. Je pensais que si je pouvais les combiner en un seul nombre à 66 chiffres puis en code 95, alors j’ai quelque chose qui peut être facilement décodé.
La chaîne encodée a fini par être plus longue que ce que j'espérais, généralement autour de 33 caractères. À ce moment-là, j'ai essayé d'utiliser un autre moyen que Java BigInteger. J'ai créé un grand nombre à partir d'un masque de 81 bits représentant les 81 cellules d'une grille, où 1 signifie qu'un indice existe pour cette cellule. J'ai ensuite combiné ce masque binaire à des représentations sur 4 bits de chaque valeur de cellule dans un ordre séquentiel, arrondi au nombre d'octets, et constaté que j'avais à peu près la même longueur de chaîne codée après codé en base95.
Je publie donc mon code au cas où quelqu'un s'intéresserait à une approche différente qui n'aurait pas si bien fonctionné.
