Single-row routing is fundamentally a routing technique for pairs of nodes arranged in a single-row *** contributes in the printed circuit hoard(PCB)design. The main objective in single-row routing is to achieve minimum congestion arising from the number of horizontal tracks in the *** results for a single layer network have been achieved through our previous model called ***,a single layer model suffers from non-tolerable lower bound values with high congestion depending on the network size. These results may further be improved by partitioning the network into two or more *** this paper,we propose a technique based on the graph partitioning concept for partitioning the nodes from a single-row network into several layers of planar *** experiment result shows that the proposed technique is able to decrease the network congestions.

In this paper we propose a new algorithm in solving constrained problem--Adaptive Quantum-behaved Particle Swarm Optimization(AQPSO).The AQPSO outperforms QPSO and PSO in global search ability and local search ability,because the adaptive method is more approximate to the learning process of social organism with high-level swarm intelligence and can make the population evolve *** adopt a non-stationary multi-stage assignment penalty in solving constrained problem to improve the convergence and gain more accurate *** approach is tested on several accredited benchmark functions and the experiment results show much advantage of AQPSO to QPSO and the traditional PSO.
