Faster Algorithms for Shortest Unique or Absent Substrings

Panagiotis Charalampopoulos, Manal Mohamed, Solon P. Pissis +2

We revisit two well-known algorithmic problems on strings: computing a shortest unique substring (SUS) and a shortest absent substring (SAS) of a string of length . Both pro…

Variations on the Problem of Identifying Spectrum-Preserving String Sets

Sankardeep Chakraborty, Roberto Grossi, Ren Kimura +3

In computational genomics, many analyses rely on efficient storage and traversal of -mers, motivating compact representations such as spectrum-preserving string sets (SPSS), whi…

Subsequence Covers of Words

Panagiotis Charalampopoulos, Solon P. Pissis, Jakub Radoszewski +3

We introduce subsequence covers (s-covers, in short), a new type of covers of a word. A word is an s-cover of a word if the occurrences of in as subsequences cover…

Counting Distinct Square Substrings in Sublinear Time

Panagiotis Charalampopoulos, Manal Mohamed, Jakub Radoszewski +3

We show that the number of distinct squares in a packed string of length over an alphabet of size can be computed in time in the word-RAM model. This paper i…

Minimizers in Semi-Dynamic Strings

Wiktor Zuba, Oded Lachish, Solon P. Pissis

Minimizers sampling is one of the most widely-used mechanisms for sampling strings. Let be a string over an alphabet . In addition, let and $k\ge…

Scalable Order-Preserving Pattern Mining

Ling Li, Wiktor Zuba, Grigorios Loukides +2

Time series are ubiquitous in domains ranging from medicine to marketing and finance. Frequent Pattern Mining (FPM) from a time series has thus received much attention. Recently, i…
