Actually, I don't know of other systems for parameter sweeps, but
I'm sure that they are out there. Simulink can probably do them.
You could look at Taverna. The parameter sweeps page below lists

Other than Kepler, do you know any other workflow system which
can do parameter sweeps until the required results are found?<br>

This is an excellent question and something I've been
meaning to try to answer in the Ptolemy II faq.<br>

How do a do a parameter sweep?</b></a> </dt>
<dd> A Parameter Sweep is when a model is run a number
of times with different parameters to perhaps find
an optimal solution. For details, see <a

<p>One way to do optimization in Ptolemy II would be
to do a parameter sweep on a model by using the
higher order component (HOC) actors such as
ModelReference. </p>

<p>It is also possible to use a state machine: </p>

<p>Another way is to invoke the model multiple times
from the command line and pass in different

can be tricky. </p>
