Abstract: This paper proposes a new method based on adjusting entropy to solve unconstrained nonlinear l_pproblem. An algorithm is given, which is convergent. The article compares this new method with the method based on maximum entropy to solve unconstrained nonlinear l_p problems by simulation. The result shows that the algorithm is effective.
