In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

The ANNs models of the periodic defected ground structures and a novel combinatorial nonperiodic defected ground structures with the characteristic of double stop band have been developed in this paper. The structure sizes of DGS and the frequencies are defined as the input samples of ANNs, the parameters of transmission coefficient calculated by FDTD method are sampled and defined as the output samples. For the PDGS with biggish structure sizes the transmission coefficients have the tiny dither owing to abnormal disturbance and the training samples have been smoothed by the least square method and five-spot triple smoothing method.
