Tasks scheduling problem is a key factor for a distributed system in order to achieve better efficiency. The problem of tasks scheduling in a distributed system can be stated as allocating tasks to processor of each computer. The objective of this problem is minimizing Makespan and communication cost while maximizing CPU utilization. Scheduling problem is known as NP-complete. Hence, many genetic...
The vertex coloring problem is a well-known classical problem in graph theory in which a color is assigned to each vertex of the graph such that no two adjacent vertices have the same color. The minimum vertex coloring problem is known to be an NP-hard problem in an arbitrary graph, and a host of approximation solutions are available. In this paper,four learning automata-based approximation algorithms...
Audio and video conferencing are two examples of the applications that need a network for providing QoS guarantee according to the available bandwidth. A very important factor in QoS is end-to-end delay. The destination node receives the packets after they go through the routers queue. Therefore, if the network guarantees the queuing delay in routers, the network will find the ability to guarantee...
