%0 Journal Article %T A New Unified Path to Smoothing Nonsmooth Exact Penalty Function for the Constrained Optimization %A Bingzhuang Liu %J Open Journal of Optimization %P 61-70 %@ 2325-7091 %D 2021 %I Scientific Research Publishing %R 10.4236/ojop.2021.103005 %X We propose a new unified path to approximately smoothing the nonsmooth exact penalty function in this paper. Based on the new smooth penalty function, we give a penalty algorithm to solve the constrained optimization problem, and discuss the convergence of the algorithm under mild conditions. %K Penalty Function %K Constrained Optimization %K Smoothing Method %K Optimal Solution %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=111223
