High query rates

This paper proposes a density optimal method, named as DO-TPR*-tree, which improves the performance of the original TPR*-tree significantly. In this proposed method, the search algorithm will enforce firing up MBR adjustment on a node, if the condition, based on density optimal for the area of its MBR, is satisfied at a query time.
