Large scale global optimization (LSGO) is a very important and extremely difficult task in optimization domain, which is urgently needed for scientific and engineering applications. Recently, decompose-and-conquer strategy has become a promising method to handle LSGO problems. In this paper, we propose a new strategy variance priority (VP) to improve the classical cooperative co-evolution framework...
The auction mechanism is widely used in Web-based sites and originally designed for human beings, but it might not be the most efficient one in the future, while, there is a demand of evolutionary computation auction agents adaptable to the dynamic auction environments. In this paper, we have applied genetic network programming (GNP) to auction agents to determine a bid at each time step and developed...
Flip-chip is a solution for designs requiring more I/O pins and higher speed. However, the higher speed demand also brings the issue of signal skew. In this paper, we propose a new 3-stage design layout methodology for flip-chip considering signal skew. Firstly, we produce an initial bumper signal assignment, and then solve the flip-chip floorplanning problem using a partitioning-based technique to...
The characteristic of wave propagation in finite elastic solids is a major issue for surface acoustic wave (SAW) devices, which are designed based on accurate analysis. As a result, it is essential in engineering applications to analyze the SAW propagation in finite piezoelectric solids with the objective of revealing the influence of structural changes. As the finite element analysis of solids is...
