Move-rb: Faster Bi-Directional r-indexes and Approximate Pattern Matching
Approximate pattern matching (APM) on highly repetitive texts is a central task in bioinformatics. Bi-directional r-indexes support left- and right-extension of a pattern and thereby accelerate APM algorithms based on search schemes, but existing variants -- br-index and b-move -- suffer from two bottlenecks: $O(\sigma...
