Dominating set problems are among the most important class of combinatorial in graph optimization, from a theoretical as well practical point view. In this paper, we address recently introduced (minimum) weighted total domination problem. problem, given an undirected with vertex weight function and edge function. The goal is to find dominating D minimal weight. A subset vertices such that every...

this paper deals with the product mix problem using the concept of theory of constraints (toc). theory of constraints is one of the most efficient approaches which have been applied to solve the product mix problem heuristically. although there are numerous heuristic and meta-heuristics to solve this problem, finding the optimal solution in a reasonable time is still a challenging issue. in thi...

Loop layout is a common in the Flexible Manufacturing Systems (FMS), machines arranged around loop and materials are transported unidirectional only. The intention of problem (LLP) determination regulating loop, to minimize maximum congestion among family parts. Artificial immune system (AIS) algorithm, Tabu Search (TS) Improved (ITS) algorithms employed solve these problems. algorithm tested v...

Today, Robotic is an essential technology from the entertainment to the industry. Thousands of articles have been published on Robotic. There are various types of robots such as parallel robots, industrial robots, mobile robots, autonomous mobile robots, health-care robots, military robots, entertainment robots, nano robots and swarm robots. So, this variety brings a lot of problems in Robotic....
