in this paper a guided tabu search (gts) is utilized for optimal nodal ordering of finite element models (fems) leading to small profile for the stiffness matrices of the models. the search strategy is accelerated and a graph-theoretical approach is used as guidance. the method is evaluated by minimization of graph matrices pattern equivalent to stiffness matrices of finite element models. comp...

To tackle the difficulty and high cost of UAV positioning in a 5G disaster environment, this study proposes multi-UAV coordinated algorithm based on factor graph (MUAV-FGC). A model is designed for master-slave UAVs. In process, influence speed heading errors accuracy was analyzed, expected variance values variables were used as information transmitted between factors. The error cooperative der...
