Abstract

The range minimum query problem is a widely known algorithmic problem. It is most commonly solved in a specific way: First preprocessing the array by calculating minima for some intervals, then combining a constant number of the minima to answer queries.


We developed a general notion of these data structure, called k-coverings, where the k stands for the maximal number of intervals we combine to answer each query. This allowed us to discover tight bounds for 2-, 3- and k-coverings with k ≥ 3. In this talk we will look at multiple k-covering data structures, derive upper bounds from them and
understand the proof for the tight bound Θ(n log(log n)) for 3-coverings.
