Finding approximate palindromes in strings
We introduce a novel definition of approximate palindromes in strings, and
provide an algorithm to find all maximal approximate palindromes in a string
with up to errors. Our definition is based on the usual edit operations of
approximate pattern matching, and the algorithm we give, for a string of size
on a fixed alphabet, runs in time. We also discuss two
implementation-related improvements to the algorithm, and demonstrate their
efficacy in practice by means of both experiments and an average-case analysis
