A stack is an ordered collection of items for which we can only add or remove items from one end (the top of the stack). The stack is another container class, much like a list, but with a much more limited set of operations: push, pop and size . The proposed work presents a ...
【LRU Cache】Design and implement a data structure for Least Recently Used (LRU) cache. It should support the following operations: get and put. get(key) - Get the value (will always be positive) of the key if the key exists in the cache, otherwise return -1. put(key, value) - Set...
fromString public static Algorithm fromString(String name) Creates or finds a Algorithm from its string representation. Parameters: name - a name to look for. Returns: the corresponding Algorithm.values public static Collection values() Gets known Algorithm values. Returns: known Algorithm values....

The recursive solution of implementing DFS is like below, the idea is to use the call stack of the recursive function to perform DFS. time = 1 dfs(node source) { mark source.discover = time++; for each child node c of source { dfs(c); } mark source.finish = time++; } Each time...
Further proposed algorithm allow self managed VM placement strategy (best mapping between physical host and deployed virtual machines) and improve QoS parameters at Openstack cloud environment. A new algorithm (Hybrid Cloud Optimized Cost scheduling) based upon elasticity concept has been proposed by L...
The system described herein improves on Sagiv's algorithm in two respects: First, it avoids an inefficiency of Sagiv's algorithm, namely that operations may get “lost” while trying to locate a data record and have to be restarted; second, it introduces a scheme for garbage-collecting deleted...
For the sake of verifying the performance of SSO when applied on practical PEMFC parameter estimation, NedStack PS6 PEMFC stack has been used for feasibility evaluation (El-Fergany, 2018a). Simulation results show that SSO can achieve desirable results with high convergence speed compared with other...
