%To solve optimization problem:
%Create a new subfolder in ...\PSG\MATLAB:
%..\PSG\MATLAB\problem_MaxRet_Prob
%Download and unpack the following zipped file from 'Data' to the created folder:
%'Mat_data_problem_MaxRet_Prob.zip'
%Run program 'problem_MaxRet_Prob.m'
%=======================================================================

clc;
clear;
addpath('..');

%Load data:
load('.\problem_MaxRet_Prob_data.mat')
%Define options for PSG solver:
stroptions.Precision = 9;
stroptions.Stages = 10;
%Define input arguments:
string1 = {};
string2 = {'pr_pen'};
w2 = {0.02};

%Solve optimization problems:
[xout, fval, status, output] = riskconstrprog([], string2, [], [], [], [], w2, H2, [], [], d, r, [], [], Aeq, beq, lb, ub, [], stroptions);
 
%Display results:
disp(' ');

%Display status of optimization problem:

%Display optimal point:
