Fully functional suffix trees and optimal text searching in BWT-runs bounded space

T Gagie, G Navarro, N Prezza - Journal of the ACM (JACM), 2020 - dl.acm.org
… They regard the collection as a single concatenated text T[1 . .n] with separator symbols, …
However, they are unable to locate where those positions are in T unless they add a set of …

Succinct colored de Bruijn graphs

…, PS Morley, KE Belk, R Raymond, T Gagie… - …, 2017 - academic.oup.com
… Since the eighth 1 in B L is B L [ 10 ] and it is preceded by two 0s, we see that ACG’s outgoing
edges’ labels are in EBWT [ 8..10 ] ⁠, so they are A, C and T. Suppose we want to follow …

MONI: a pangenomic index for finding maximal exact matches

M Rossi, M Oliva, B Langmead, T Gagie… - Journal of …, 2022 - liebertpub.com
Recently, Gagie et al. proposed a version of the FM-index, called the r-index, that can store
thousands of human genomes on a commodity computer. Then Kuhnle et al. showed how to …

New algorithms on wavelet trees and applications to information retrieval

T Gagie, G Navarro, SJ Puglisi - Theoretical Computer Science, 2012 - Elsevier
… We first show that T∩ has at most α leaves of T. The leaves of T∩ that are also leaves of T
correspond to the symbols that belong to the intersection, and thus to the number of 0s in any …
