2011 Lecture Notes in Computer Science  
We obtain also some relevant byproducts on compressed suffix trees.  ...  Their time complexities are not optimal, however: they always depend on the alphabet size.  ...  While remarkable in terms of space, self-indexes have not retained the time complexities of the classical suffix trees and arrays. Table 1 lists the current space-optimal self-indexes.  ...

Improved count suffix trees for natural language data

Guido Sautter, Cristina Abba, Klemens Böhm
2008 Proceedings of the 2008 international symposium on Database engineering & applications - IDEAS '08  
Optimizing queries with predicates includes (sub)string estimation, i.e., estimating the selectivity of query terms based on small summary statistics before query execution.  ...  Existing pruning techniques are based on suffix frequency or tree depth.  ...  CONCLUSIONS Estimating the selectivity of query terms is essential for query optimization. For string predicates, estimation frequently relies on Count Suffix Trees (CST) [3, 6, 7] .  ...

2012 Journal of Discrete Algorithms  
For indexed searching we achieve indexes that are as fast as the classical suffix array, yet occupy less than 50% extra space (instead of the usual 400%).  ...  Optimal sampling Suppose that we have enough space to create the sampled suffix array for b · n suffixes where 0 < b < 1.  ...  We index B for select B queries.  ...

2014 ACM Transactions on Algorithms  
Their time complexities are not optimal, however; in particular they are always multiplied by a factor that depends on the alphabet size.  ...  In this paper we achieve, for the first time, full alphabet-independence in the time complexities of self-indexes, while retaining space optimality. We obtain also some relevant byproducts.  ...  It is open whether one can achieve optimal times within optimal space (say, under the H k (T ) entropy model).  ...
