克隆 Clone
标准数独基础上,涂色区域内,相同的位置上拥有相同的数字。换句话说,涂色区域是完全一致的,就像是克隆一样。
Classic rules applied. Additionally, numbers in same position in colored zones should be same. In other way, the colored zones should be competely same, just like clone.
◆显性唯一Naked Singles
候选数可以通过不同的克隆单元格进行删除。
Candidates may be deleted in different cloning cells.
◆隐性唯一 Hidden Singles
某部分涂色区域不是A,则其余涂色区域中,对应的位置也不能是A。此外,我们还可以基于行列宫,来考虑区域的互补性。例如,在这个例题中,A5、A6和F1、F2拥有相同的数字组合。
When a part in a colored zones cannot be A, the corresponding part in other colored zones cannot be A either. Additionally, we can consider about the complementariness of colored zones. In this example, A5 and A6 is the same group of F1 and F2.
◆代数 Unknown Covering
