test_opt
test_opt,
an Octave code which
defines test problems for the scalar function optimization problem.
The scalar function optimization problem is to find a value
for the N-dimensional vector X which minimizes the value of
the given scalar function F(X). The function F(X) is
not usually defined as the sum of squares of other functions.
The minimum function value is not guaranteed to be zero.
Any system of M nonlinear functions in N unknowns can be turned into
a scalar optimization problem. One way to do this is to define the functional
F(X) to be the sum of the squares of the original nonlinear functions.
The minimizer of F will then minimize the sum of the squares of the
residuals. Since this process involves squaring, it can be less accurate
than dealing directly with the original nonlinear functions: that is to say,
the derived optimization problem may be more convenient to solve, but might
provide less accurate results than applying a nonlinear solver to the original
system.
If a function F(X) is differentiable, then at an optimum, the
gradient vector must vanish. Thus, it is also possible to start with an
optimization problem involving F(X) and turn it into a problem in
which we seek a zero of the nonlinear functions represented by the gradient
of F. Of course, the gradient must be zero at a mininum, but
the converse does not hold; thus unless we know more about F, it is not
safe to try to replace the optimization problem by a nonlinear function
solution.
For each test problem, routines are provided to evaluate the function,
gradient vector, and hessian matrix. Routines are also provided to
indicate the number of variables, the problem title, a suitable starting
point, and a minimizing solution, if known.
