快速简单地在字符串中查找近似回文

Finding Approximate Palindromes in Strings Quickly and Simply

L. Allison

摘要:

描述了两种算法,以找到长的近似回文在一个字符串,例如DNA序列。一个简单的算法需要O(n)空间,并且几乎总是在$O(k.n)$时间内运行,其中n是字符串的长度,k是回文中允许的“错误”的数量。它的最坏情况的时间复杂度是$O(n^2)$,但这不会发生在真实的生物序列。更复杂的算法保证了$O(k.n)$的最差时间复杂度。

英文摘要:

Described are two algorithms to find long approximate palindromes in a string, for example a DNA sequence. A simple algorithm requires O(n)-space and almost always runs in $O(k.n)$-time where n is the length of the string and k is the number of ``errors'' allowed in the palindrome. Its worst-case time-complexity is $O(n^2)$ but this does not occur with real biological sequences. A more complex algorithm guarantees $O(k.n)$ worst-case time complexity.
