| Abstract: | Aiming at problems of large scale spare parts and cloth optimizing, this paper analyzes the application of improved generic algorithm in the irregular graph stock layout, and researches the advantage and disadvantage of generic algorithm in the intelligent optimizing stock layout. Based on conventional generic algorithm, it puts forward an improved algorithm which classifies graph group by their similarity degree in order to simplify time complicity of generic algorithm. Experimental results prove that this means outgoes the conventional one in time complicity, so it is applied to large scale of graph stock layout system. |
