Longest Unbordered Factor in Quasilinear Time
Tomasz Kociumaka, Ritu Kundu, Manal Mohamed +1
A border u of a word w is a proper factor of w occurring both as a prefix and as a suffix. The maximal unbordered factor of w is the longest factor of w which does not have a borde…

Near-Optimal Computation of Runs over General Alphabet via Non-Crossing LCE Queries
Maxime Crochemore, Costas S. Iliopoulos, Tomasz Kociumaka +5
Longest common extension queries (LCE queries) and runs are ubiquitous in algorithmic stringology. Linear-time algorithms computing runs and preprocessing for constant-time LCE que…

Linear Algorithm for Conservative Degenerate Pattern Matching
Maxime Crochemore, Costas S. Iliopoulos, Ritu Kundu +2
A degenerate symbol x* over an alphabet A is a non-empty subset of A, and a sequence of such symbols is a degenerate string. A degenerate string is said to be conservative if its n…
