II Abstract Transformer core layout system research Two dimensional packing problem, a kind of Non-deterministic Polynomial Complete problem with the highest computational complexity, has a wide cross traditional boundaries of the subjects such as computational geometry, artificial intelligence, neural network and operations research. It is extensively applied to these fields of the packing problem such as apparel, mechanical manufacture, glass and other industries. Researching on the nesting problem not only brings incalculable economic values and social values, but also promotes the social development oriented to the environmental protection and saving resource direction. With the constant development and update of the computer tech
