Instance-Optimal Geometric Algorithms
We prove the existence of an algorithm A for computing 2-d or 3-d convex hulls that is optimal for every point set in the following sense: for every set S of n points and for ever...

Succinct Suffix Arrays Based on Run-Length Encoding
A succinct full-text self-index is a data structure built on a text T = t1t2 . . . tn, which takes little space (ideally close to that of the compressed text), permits efficient se...
