Finding Distinct Subpalindromes Online

Abstract:
We exhibit an online algorithm finding all distinct palindromes inside a given string in time Θ(n log |Σ|) over an ordered alphabet and in time Θ(n |Σ|) over an unordered alphabet. Using a reduction from a dictionary-like data structure, we prove the optimality of this algorithm in the comparison-based computation model.
