In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation.It can produce either a postfix notation string, also known as reverse Polish notation (RPN), or an abstract syntax tree (AST). [1]
The block-stacking problem is the following puzzle: Place N {\displaystyle N} identical rigid rectangular blocks in a stable stack on a table edge in such a way as to maximize the overhang. Paterson et al. (2007) provide a long list of references on this problem going back to mechanics texts from the middle of the 19th century.
This is a new eviction algorithm designed in 2023. Compared to existing algorithms, which mostly build on LRU (least-recently-used), S3-FIFO only uses three FIFO queues: a small queue occupying 10% of cache space, a main queue that uses 90% of the cache space, and a ghost queue that only stores object metadata.
it uses a stack instead of a queue, and; it delays checking whether a vertex has been discovered until the vertex is popped from the stack rather than making this check before adding the vertex. If G is a tree, replacing the queue of the breadth-first search algorithm with a stack will yield a depth-first search algorithm. For general graphs ...
Jockeying: customers switch between queues if they think they will get served faster by doing so; Reneging: customers leave the queue if they have waited too long for service; Arriving customers not served (either due to the queue having no buffer, or due to balking or reneging by the customer) are also known as dropouts. The average rate of ...
By Leah Douglas and Ted Hesson. WASHINGTON (Reuters) - U.S. farm industry groups want President-elect Donald Trump to spare their sector from his promise of mass deportations, which could upend a ...
A queue may be implemented as circular buffers and linked lists, or by using both the stack pointer and the base pointer. Queues provide services in computer science , transport , and operations research where various entities such as data, objects, persons, or events are stored and held to be processed later.
