We present a new algorithm for generating super condensed
neighbourhoods. Super condensed neighbourhoods have recently been
presented as the minimal set of words that represent a pattern
neighbourhood. These sets play an important role in the generation
phase of hybrid algorithms for indexed approximate string matching.
An existing algorithm for this purpose is based on a dynamic
programming approach, implemented using bit-parallelism. In this work
we present a bit-parallel algorithm based on automata which is faster,
conceptually much simpler and uses less memory than the existing
method.
