Practical Entropy-Bounded Schemes for O(1)-Range Minimum Queries
The Range Minimum Query (RMQ) Problem is to preprocess an array A of length n in O(n) time such that subsequent on-line queries asking for the position of a minimal element between...

What's Decidable about Sequences?
Abstract. We present a first-order theory of (finite) sequences with integer elements, Presburger arithmetic, and regularity constraints, which can model significant properties of ...

Towards Optimal Range Medians
We consider the following problem: given an unsorted array of n elements, and a sequence of intervals in the array, compute the median in each of the subarrays defined by the inter...

A Verifiable, Control Flow Aware Constraint Analyzer for Bounds Check Elimination
The Java programming language requires that out-of-bounds array accesses produce runtime exceptions. In general, this requires a dynamic bounds check each time an array element is...

Sorting Multisets Stably in Minimum Space
Abstract. In a decision tree model, (n log2 n m i=1 ni log2 ni + n) is known to be a lower bound for sorting a multiset of size n containing m distinct elements, where the ith dist...
