In the Optimization or Parameter Estimation widget you may select a any combination of parameters. If you are stuck in a local minimum it is best to select all parameters by first selecting the first and then clicking on the last while pressing the shift key. After you have selected the parameters you would like to change use the tool button to the right of the “Start Value” and press “Random”. You may also revert to the current model parameters or change the start values individually.
