Description

Case study Intensity-Modulated Radiation Therapy Treatment Planning Problem (see Formal Problem Statement) in MATLAB Environment is solved with riskprog PSG subroutine.

 

MATLAB code for Intensity-Modulated Radiation Therapy Treatment Planning Problem is in file problem_men_short.m.

Data are saved in files problem_men_short_data.mat .

 

MATLAB code

Let us describe the main operations. To run case study you need to do the following main steps:

 

In file problem_men_short.m:

 

Load data:

 

load('.\problem_men_short_data.mat')

 

Define options for PSG solver:

 

stroptions.Solver = 'BULDOZER';

stroptions.Precision = 9;

 

Define input arguments:

 

string = {'pm2_pen_g'};

w = {0};

 

Optimize problem:

 

 

Display solution:

 

disp(' ');

disp('Results: ');

 

Display status of optimization problem:

 

disp(sprintf('status of optimization problem = %s', status));

 

Display solving time:

 

disp(sprintf('solving time = %g', output.solving_time));

 

Display objective:

 

disp(sprintf('objective = %g', fval));

 

Display function:

 

disp(sprintf('pm2_pen_g= %g', output.frval));

 

Display optimal point:

 

disp('optimal point = ');

disp(xout');
