(In spite of shortcoming of matlab 7.0 that it can t provide the toolbox in order to dealing with general integer programming problem, therefore, we need goog algorithm to write matlab code to solve general integer programming， in 2006, Li duan from Hongkong university and Sun xiaoling from Fudan university proposed a book named Nonlinear Integer programming, and it include the problems as follows: lagrangian duality problem surrogate duality problem nonlinear lagrangian problem nonlinear knapsack problem nonlinear integer programming with a quadratic objective functions nonconstrained polynomial 0-1 optimization constrained polynomial 0-1 programming mixed-integer nonlinear programming)
