13  Unconstrained Optimization

The TOMLAB bundle testprob provides two sets of test problems for unconstrained optimization problems (with simple bounds): uc_prob, and uhs_prob.

13.1  An example of a unconstrained optimization problem (with simple bounds)

The basic structure of a unconstrained optimization problems (with simple bounds) is the following

 
min
x
f(x)
   
s/t
−∞ < xL x xU < ∞
    (15)


where x, xL, xU ∈ Rn and f(x) ∈ R.

13.2  uc_prob

In glo1_prob there are 17 unconstrained optimization problems (with simple bounds) with up to three variables. In order to define the problem n and solve it execute the following in Matlab:
  Prob   = probInit('uc_prob',n);
  Result = tomRun('',Prob);

13.3  uhs_prob

In glo2_prob there are 25 unconstrained optimization problems (with simple bounds) with up to 10 variables. In order to define the problem n and solve it execute the following in Matlab:
  Prob   = probInit('uhs_prob',n);
  Result = tomRun('',Prob);
