Optimal Purely Functional Priority Queues
... each link corresponding to a carry. The worst case is insertion into a queue of size n = 2k − 1, requiring a total of k links and O(log n) time. The analogy to binary addition also applies to melding two queues. We step through the trees of both queues in increasing order of rank, linking trees of e ...

Efficient Data Structures and Algorithms for Range
... Let S be a set of n points in the two dimensional plane. A point p = (px , py ) is said to dominate another point q = (qx , qy ) if px > qx and py > qy . Points not dominated by any point in the set are called maximal or skyline points. We preprocess S into a data structure such that we can efficien ...

... Interestingly, data structures used in purely functional programs do not necessarily need to be implemented in a purely functional way. It is sufficient for a structure to behave as if it was never modified, even though the implementation may utilize assignments and modify existing values. This leads t ...
