Planar orthogonal straight-line drawing algorithm of planar graph based on genetic algorithm

A new planar graph planar orthogonal straight-line drawing algorithm is proposed which is based on genetic algorithm. The algorithm transforms the problem of planar graph drawing to that of constraint optimization, and constructs a function with constraints according to the aesthetic criteria of graph drawing problem, and then uses genetic algorithms to find approximate optimal solutions to the objective function, and thus obtains a planar orthogonal straight-line drawing of the planar graph. The new algorithm is of following advantages: the method is simple and it is easier to be implemented and also the figure drawn is beautiful, finally, the algorithm is stable. The experiment results show that the final results of the drawing algorithm don't rely on the initial status of graphs.
