Searching for gapped palindromes

AbstractWe study the problem of finding, in a given word, all maximal gapped palindromes verifying two types of constraints, that we call long-armed and length-constrained palindromes. For each of the two classes, we propose an algorithm that runs in time O(n+S) for a constant-size alphabet, where S is the number of output palindromes. Both algorithms can be extended to compute biological gapped palindromes within the same time bound
