For nonlinear l1 problembased on the conditions for optimality of the nonlinear l1 problem in [1], we first discuss the descent direction of the objective function F(x) in theory , further more , we study the relation between the optimal solution of nonlinear l1 problem and the optimal solution of some kind of quadratic programming problem with box constrains.
