- W1966892175 abstract "A weak heap is a priority queue that supports the operations construct, minimum, insert, and extract-min. To store n elements, it uses an array of n elements and an array of n bits. In this paper we study different possibilities for optimizing construct and insert such that minimum and extract-min are not made slower. We provide a catalogue of algorithms that optimize the standard algorithms in various ways. As the optimization criteria, we consider the worst-case running time, the number of instructions, branch mispredictions, cache misses, element comparisons, and element moves. Our contributions are summarized as follows: The standard algorithm for construct runs in O(n) worst-case time and performs n−1 element comparisons. Our improved algorithms reduce the number of instructions, the number of branch mispredictions, the number of element moves, and the number of cache misses. Even though the worst-case running time of the standard insert algorithm is logarithmic, we show that—in contrast to binary heaps—n repeated insert operations require at most 3.5n+O(lg2n) element comparisons. We improve a recent result of ours, in which we achieve O(1) amortized time per insertion, to guarantee O(1) worst-case time per insertion. After the deamortization, minimum still takes O(1) worst-case time and involves no element comparisons, and extract-min takes O(lgn) worst-case time and involves at most lgn+O(1) element comparisons. This constant-factor optimality concerning the number of element comparisons has previously been achieved only by pointer-based multipartite priority queues." @default.
