A palindrome is a string that reads the same forward and backward. For a string x, let Pals(x) be the set of all maximal palindromes of x, where each maximal palindrome in Pals(x) is encoded by a pair (c, r) of its center c and its radius r. Given a text t of length n and a pattern p of length m, the palindrome pattern matching problem is to compute all positions i of t such that Pals(p) = Pals(t[i:i + m - 1]). We present linear-time algorithms to solve this problem.
