Do We Really Need to Balance Patricia Tries?
In this paper, we give exact and asymptotic approximations for variance of the external path length in a symmetric Patricia trie. The problem was open up to now.

k-d range search with binary patricia tries
We use Patricia tries to represent textual and spatial data, and present a range search algorithm for reporting all k-d records from a set of size n intersecting a query rectangle. Data and queries include both textual and spatial data.

The difference between ordinary tries and Patricia tries lies in the fact that all unary nodes are removed in the latter. Their average number is thus easily determined from earlier results on the size of tries/Patricia tries.

Do we really need to balance Patricia tries? (Extended Abstract)
In this paper, we give exact and asymptotic approximations for the variance of the external path length in a symmetric Patricia trie. The problem was open up to now. We prove that for the binary Patricia trie, the variance is asymptotically equal to 0.37.

Digital trees are data structures that represent sets of strings according to their shared prefix structure. In the most fundamental of such trees, a trie, each string in the set is represented by a sequence of edges, each representing a single letter ...

Fast as a shadow, expressive as a tree: Optimized memory monitoring for C
International audienceOne classical approach to ensuring memory safety of C programs is based on storing block metadata in a tree-like datastructure. However it becomes relatively slow when the number of memory locations in the tree becomes high. Another
