C++ reference for std::priority_queue; Descriptions by Lee Killough; libpqueue is a generic priority queue (heap) implementation (in C) used by the Apache HTTP Server project. Survey of known priority queue structures by Stefan Xenos; UC Berkeley - Computer Science 61B - Lecture 24: Priority Queues (video) - introduction to priority queues ...
Priority queue: A priority queue is an abstract concept like "a list" or "a map"; just as a list can be implemented with a linked list or an array, a priority queue can be implemented with a heap or a variety of other methods. K-way merge: A heap data structure is useful to merge many already-sorted input streams into a single sorted output ...
This makes the min-max heap a very useful data structure to implement a double-ended priority queue. Like binary min-heaps and max-heaps, min-max heaps support logarithmic insertion and deletion and can be built in linear time. [3] Min-max heaps are often represented implicitly in an array; [4] hence it's referred to as an implicit data structure.
priority queue: Provides priority queue interface in terms of push / pop / top operations (the element with the highest priority is on top). Any random-access sequence supporting operations front (), push_back (), and pop_back can be used to instantiate priority_queue (e.g. vector and deque). It is implemented using a heap.

A K-D heap [1] is a data structure in computer science which implements a multidimensional priority queue without requiring additional space. It is a generalization of the Heap . [ 2 ] It allows for efficient insertion, query of the minimum element, and deletion of the minimum element in any of the k dimensions, and therefore includes the ...
In computer science, the Brodal queue is a heap/priority queue structure with very low worst case time bounds: () for insertion, find-minimum, meld (merge two queues) and decrease-key and (()) for delete-minimum and general deletion. They are the first heap variant to achieve these bounds without resorting to amortization of operational costs.
The first version combines the properties of the double-ended queue (deque) and a priority queue and may be described as an ordered deque.. An item may be added to the head of the list if the new item is valued less than or equal to the current head or to the tail of the list if the new item is greater than or equal to the current tail.
