Mergeable Dictionaries With Shifts

Philip Bille, Mikko Berggren Etienne, Inge Li Gørtz

We revisit the mergeable dictionaries with shift problem, where the goal is to maintain a family of sets subject to search, split, merge, make-set, and shift operations. The search…

Compressed Communication Complexity of Longest Common Prefixes

Philip Bille, Mikko Berggreen Ettienne, Roberto Grossi +2

We consider the communication complexity of fundamental longest common prefix (Lcp) problems. In the simplest version, two parties, Alice and Bob, each hold a string, and ,…

Decompressing Lempel-Ziv Compressed Text

Philip Bille, Mikko Berggren Ettienne, Travis Gagie +2

We consider the problem of decompressing the Lempel--Ziv 77 representation of a string of length using a working space as close as possible to the size of the input. Th…

Fast Dynamic Arrays

Philip Bille, Anders Roy Christiansen, Mikko Berggren Ettienne +1

We present a highly optimized implementation of tiered vectors, a data structure for maintaining a sequence of elements supporting access in time and insertion and delet…

Time-Space Trade-Offs for Lempel-Ziv Compressed Indexing

Philip Bille, Mikko Berggren Ettienne, Inge Li Gørtz +1

Given a string , the \emph{compressed indexing problem} is to preprocess into a compressed representation that supports fast \emph{substring queries}. The goal is to use lit…

Multi-Agent Programming Contest 2012 - The Python-DTU Team

Jørgen Villadsen, Andreas Schmidt Jensen, Mikko Berggren Ettienne +3

We provide a brief description of the Python-DTU system, including the overall design, the tools and the algorithms that we plan to use in the agent contest.
