Dequeue i and report it as third nearest neighbor.
A worker thread in the pool
dequeues (4) the next request from the head of the queue and dispatches it (5).
Finally, VF and NVF flows
dequeue traffics in well manner to the destination over WLANs.
[Q.sub.in] and [Q.sub.out], which are accessed by the scheduler and the workers, are required to support concurrent enqueue and
dequeue operations.
Note that violated preconditions in enqueue and
dequeue may raise exceptions in cases where blocking would be appropriate--we will return to this later.
Assuming the ADT has operations to enqueue and
dequeue items, the processes may execute an operation Q$Enqueue (job) to add a new job to the queue, and they may execute an operation Q$Dequeue (job) to fetch a job from the queue.
Consider a queue which is manipulated using enqueue and
dequeue transactions (which deal with one element).
RCs
dequeue requests and process transactions on their behalf.
These queues must support a get-length operation in addition to enqueue and
dequeue, which slightly complicates their implementation.
[1972] have shown, however, that a queue (or even a
dequeue, where items can be added or removed from either end) can be implemented in pure Lisp with O(1) primitive Lisp operations being performed for each queue (or
dequeue) operation.
request to
dequeue whenever the forward scan fails to find anything in an entire "year."
Consider two abstract types Queue and
DEQueue (doubly ended queue).
