Abstract
The Directed Acyclic Word Graph (DAWG) is an efficient data structure used
to treat and analyze repetitions in texts,
especially in DNA genomic sequences.
Here, we consider the Compact Directed Acyclic Word Graph of a word.
We give the first direct algorithm to construct it.
It runs in time linear in the length of the string on a fixed alphabet.
Our implementation requires half the memory space used by ordinary DAWGs.
