Java, 330 punktów
Zanim wyśmiewam się z tak wysokiego wyniku, pozwólcie, że wyjaśnię, że próbowałem rozwiązać ten problem w inny sposób, wiedząc, że prawdopodobnie nie będzie on tak optymalny, jak niektóre lepsze odpowiedzi tutaj. Byłem mniej więcej ciekawy, czy uda mi się zbliżyć co ku mojemu zaskoczeniu nie zdawałem sobie sprawy, o ile gorzej by się okazało. Oto podsumowanie mojego podejścia:
Opracuj algorytm rozwiązywania zagadek sudoku.
Opracuj mieszające się algo, które nadal będzie możliwe do rozwiązania. Robi to nieco losowo, jednocześnie usuwając wskazówki, które można trywialnie ustalić przed ręką. Mogłem rzetelnie uzyskać około 22 wskazówek, zanim zajęło to zdecydowanie zbyt dużo czasu.
Raz zaszyfrowana łamigłówka może być reprezentowana przez trójkę liczb całkowitych jednocyfrowych dla każdej wskazówki, w moim przypadku 22 trojaczki po 3. Pomyślałem, że jeśli mogę połączyć je w jedną 66 cyfr, to kodowanie kodu base95 to mam coś, co może łatwo dekodować.
Zakodowany ciąg okazał się dłuższy, niż się spodziewałem, na ogół około 33 znaków. W tym momencie wypróbowałem alternatywny sposób niż użycie Java BigInteger, w którym utworzyłem dużą liczbę z 81-bitowej maski reprezentującej 81 komórek siatki, gdzie 1 oznacza wskazówkę dla tej komórki. Następnie połączyłem tę maskę bitową z 4-bitowymi reprezentacjami każdej wartości komórki w kolejności sekwencyjnej, zaokrąglając w górę do bajtów i stwierdziłem, że z grubsza otrzymałem taką samą długość łańcucha po kodowaniu base95.
Zasadniczo więc publikuję swój kod na wypadek, gdyby ktoś był zainteresowany innym podejściem, które nie wyszło tak dobrze.
