摘要

The suffix tree is an extremely important data structure for stringology, with a wealth of applications in bioinformatics. Classical implementations require much space, which renders them useless for large problems. Recent research has yielded two implementations, offering widely different space-time tradeoffs. However, each of them has practicality problems regarding either space or time requirements. In this paper we implement a recent theoretical proposal and show it yields an extremely interesting structure that lies in between, offering both practical times and affordable space. The implementation is by no means trivial and involves significant algorithm engineering.
