4.5.6 Parameters in the Experiment File

In the previous examples only some of the parameters in the experiment file have been explained. A complete list of available parameters is shown in Table 4.4. Some of these values are directly passed to the optimizer executable and therefore described in the appropriate sections. The column ``type'' indicates if this parameter is only available for the least-squares algorithm (l) or for the nonlinear constrained optimizer (d) or for both (b).


Table 4.4: Description of the parameters available in the experiment file.
Parameter Type Description
model b The file name of the model which has to be evaluated.
free b A list of names of parameters which can be controlled by the optimizer. These names must exist as an input port of a model. The values for the start, minimum and maximum value are taken from the definitions of the model.
target b The target function of the evaluated model. This name must exist as and output port of a model. For a nonlinear constrained optimization problem the output port must be a scalar and for a least-squares problem it must be a vector.
dimension l The dimension of the target vector can be assigned with this optional parameter. If it is omitted the dimension is probed by a model evaluation before starting the optimization process.
tolerance l See Table F.2.
equality-constraint d This variable assigns the equality constraints which have to satisfied by the optimizer. The given list of names selects the output ports of the evaluated model passed to the optimizer.
inequality-constraint d Assigns the inequality-constraint described in equality-constraint
tau0 d See Table H.1.
del0 d See Table H.1.
nreset d See Table H.1.
epsdif d See Table H.1.
gradient b See Table H.1 or Table F.2.
log b The file name or an optional log-file can be given here. In this file all evaluation requests are written.
dump b In this file the curves are stored. This is very useful for batch execution.
chkptfile b With this variable the file name where an image of the optimizer memory is dumped can be set. For more information see Section 4.5.2 and Table H.1 or Table F.2.
