We describe a data structure, the tiered vector, which is an implementation of the Vector ADT that provides O(1/)worst case time performance for rank-based retrieval and O(n ) amortized time performance for rank-based insertion and deletion, for any fixed > 0. We also provide results from experiments involving the use of the tiered vector for = 1/2 in JDSL, the Data Structures Library in Java.
