Recently Kubica et al. (Inf. Process. Let., 2013) and Kim et al. (submitted to Theor. Comp. Sci.) introduced order-preserving pattern matching. In this problem we are looking for c…
Note on the Greedy Parsing Optimality for Dictionary-Based Text Compression
Maxime Crochemore, Alessio Langiu, Filippo Mignosi
Dynamic dictionary-based compression schemes are the most daily used data compression schemes since they appeared in the foundational papers of Ziv and Lempel in 1977, commonly ref…
The Rightmost Equal-Cost Position Problem
Maxime Crochemore, Alessio Langiu, Filippo Mignosi
LZ77-based compression schemes compress the input text by replacing factors in the text with an encoded reference to a previous occurrence formed by the couple (length, offset). Fo…
Fewest repetitions in infinite binary words
Golnaz Badkobeh, Maxime Crochemore
A square is the concatenation of a nonempty word with itself. A word has period p if its letters at distance p match. The exponent of a nonempty word is the quotient of its length…
