Software pipelining is becoming widely used as a loop execution model for microprocessors supporting a high instruction level parallelism. In this paper we describe a heuristic method for software pipelining, named Graph Traverse Software Pipelining (GTSP), that divides the scheduling problem in two phases: scheduling on a graph and code generation. The first phase encapsulates the NP-complete ...

this study focused on the optimization of al—mg to cuzn34 friction stir lap welding (fslw) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using grey relational analysis (gra). first, the degree of freedom was calculated for the system. then, the experiments based on the target values and number of considered levels, corresponding orth...

The arc costs are assumed to be online parameters of the network and decisions should be made while the costs of arcs are not known. The policies determine the permitted nodes and arcs to traverse and they are generally defined according to the departure nodes of the current policy nodes. In on-line created tours arc costs are not available for decision makers. The on-line traversed nodes are f...
