Models Constrained Goal Attainment Problems: goals prob and mco prob
This page is part of TOMLAB Models. See TOMLAB Models. |
The TOMLAB bundle testprob provides two sets of problems for constrained goal attainment problems: goals_prob and mco_prob.
An example of a constrained goal attainment problems
The basic structure of a constrained goal attainment problems is the following:
Failed to parse (unknown function "\multicolumn"): {\displaystyle \begin{array}{cccccc} \min\limits_x & \multicolumn{5}{l}{\max \ \ lam: r(x) - w * lam \leq g} \\ \mbox{subject to} & x_L & \leq & x & \leq & x_U \\ {} & b_L & \leq & Ax & \leq & b_U \\ {} & c_L & \leq & c(x) & \leq & c_U \\\end{array} }
where , , , , , , and .
An example of a problem of this class, (that is also found in the TOMLAB quickguide) is goalsQG:

r: Residual vector J: Jacobian matrix c: Nonlinear constraint vector dc: Nonlinear constraint gradient matrix
The following file illustrates how to define and solve a problem of this category in TOMLAB.

mco_prob
In glb_prob there are 9 Multi-Criterium unconstrained and constrained nonlinear test problems with up to 10 variables and few constrains. In order to define the problem n and solve it execute the following in Matlab:
Prob = probInit('mco_prob',n); Result = tomRun('',Prob);
goals_prob
In goals_prob there are 9 constrained goal attainment test problems with sizes to 9 variables and about 10 constrains. In order to define the problem n and solve it execute the following in Matlab:
Prob = probInit('goals_prob',n); Result = goalSolve(Prob,1);
