Brodal queue

In computer science, the Brodal queue is a heap/priority queue structure with very low worst case time bounds: O(1) for insertion, find-minimum, meld (merge two queues) and decrease-key and O(\mathrm{lg} n) for delete-minimum and general deletion; they are the first heap variant with these bounds. Brodal queues are named after their inventor Gerth Stølting Brodal.[1]

While having better asymptotic bounds than other priority queue structures, they are, in the words of Brodal himself, "quite complicated" and "[not] applicable in practice."[1]
