SOLUTION:
Move B4 R for a match of 4
Move D4 L for a match of 4
Move B3 L for a match of 3
Move B5 D for a match of 3
Move C3 D for a match of 3
Move C5 U for a match of 3
Move D4 D for a match of 3
Move E4 R for a match of 3
Move F3 L for a match of 3
Эта программа может работать с платой любого размера.Программа основана на том, как я ищу совпадения в игре (я предполагаю, что это грубая сила).
Редактировать
Похоже, что решатель не смог найти совпаденияна первом драгоценном камне (см. образец ниже).
5, 2, 5
2, 5, 3
1, 5, 4
Если бы алгоритм был применен к примеру выше, совпадений не будет найдено.
Я исправил это сейчас.Теперь существует метод IsMatchOnFirst() для обработки этих случаев.
См. Обновленный код для изменений.
