Abstract: To enhance the design efficiency of the fractal artistic pattern，a new method of fractal pattern generation based on Interactive Genetic Algorithm（IGA） is proposed.In the method，the binary tree structure is used as the expression of iterated functions of fractal pattern，and crossover，mutation and selection are operated on the iterated functions with tree structure for producing new offspring.Furthermore，the subjective evaluation errors are reduced greatly and the evaluation mechanism is optimized with the integration of the users’ communizing and satisfying fitness function.The method provided a better help to meet the demands of character-seekers design.The feasibility and practicality of Interactive Genetic Algorithm by application is also proved.
