Double-ended priority queue: Applications & Science

In computer science, a double-ended priority queue (DEPQ) or double-ended heap or priority deque is a data structure similar to a priority queue or heap, but allows for efficient removal of both the maximum and minimum, according to some ordering on the keys (items) stored in the structure. Every element in a DEPQ has a priority or value. In a DEPQ, it…
