For the rediscovery benchmarks, FragGT is able to rediscover Celecoxib, but unable to find Troglitazone or Thiothixene. In the case of Thiothixene this is not a problem with the search algorithm but an empirical limitation in the fragment database as the tricyclic thioxanthene subgroup is not included. However, the inability to rediscovery Troglitazone suggests that a guided fragment sampling scheme would improve the FragGT approach.
