ABSTRACT

Since string operations were applied to computational biology area, various data structures and algorithms for computing efficient string operations have been studied. The maximal palindrome problem is an operation to find the maximal symmetric substrings in a string. This operation is importantly used in the string processing area such as pattern matching and likelihood measurement. In this paper, we present an algorithm to compute the maximal palindromes of the given string using three-dimensional n×n×n processors on RMESH(Reconfigurable MESH). The algorithm has O(1) constant time complexity, which is usefully used in the massive data processing areas like the computational biology.
