In recent years the field studies on collective behaviors have revealed that topological interaction of k nearest neighbors plays a the key role in flocking. In this work, we show a model of flocking through adaptation to k nearest topological neighbors, and examine the influence of the number of topological neighbors on flocking dynamics with different group size. The model is validated by simulations.
In this brief, a novel algorithm is developed for the design of infinite-impulse-response digital filters in the weighted least-squares sense. To simplify the design problem, the Levy linearized function and the Sanathanan–Koerner iterative technique are utilized. In the proposed algorithm, a denominator polynomial is decomposed as a cascade of a few second-order factors (SOFs) and a higher order...
In this paper, we proposed a global convergence of an improved filter method of feasible direction for solving inequality constrained optimization. At every trial point, it is only necessary to solve one QP sub problem with equality constraints. On contrary the traditional SQP algorithm, we use filter method with the new SQP algorithm, which avoid Maratos effect. Under some reasonable conditions,...
Fuzzy set theory is a powerful and robust mathematical frame work to handle many optimization problems. Floor planning is an important step in the physical design of VLSI circuits, whose goal is to optimize the layout of the chip. With the development of IC designs, more and more issues need to be considered. As a multi-objective optimization problem (MOP), it is very difficult for floor planning...
