They provide an analogy to help one understand what a priority queue is.

A priority queue is often considered to be a "container data structure".

It must have a complex interrupt process, with food orders at the top of the priority queue.

All other traffic can be handled when the highest priority queue is empty.

Another approach used is to send disproportionately more traffic from higher priority queues.

A priority queue must at least support the following operations:

A standard approach here is to check if a node about to be added already appears in the priority queue.

Priority queue is divided into 4 sub queues with different priorities.

However, any creditor who had contracted for a security interest would be first in the priority queue.

Data in each queue are only served when the higher priority queues are empty.

There are a variety of simple, usually inefficient, ways to implement a priority queue.

Backtracking is according to a priority queue based on closeness.

In this method two different priority queues for min and max are maintained.

A sorting algorithm can also be used to implement a priority queue.

Create a leaf node for each symbol and add it to the priority queue.

This operation and its O(1) performance is crucial to many applications of priority queues.

Heapsort if the priority queue is implemented with a heap.

Another use of a priority queue is to manage the events in a discrete event simulation.

Redo step 3 until the priority queue is empty.

Insertion sort if the priority queue is implemented with an ordered array.

The first detail to note is that the way the priority queue handles ties can have a significant effect on performance in some situations.

The algorithm is based on the soft heap, an approximate priority queue.

One example application of the double-ended priority queue is external sorting.

Efficient selection of the current best candidate for extension is typically implemented using a priority queue.

Each certificate change requires a delete and insert operation in the priority queue of events.
