I see on github that you are writing optimization code using Python. When using non-linear solvers such as Levenberg-Marquardt or gradient descent to optimize parameters for non-linear regression, the…

## Expected Behavior
Experimental parameters tune themselves to get the "best" data or focus on the "most interesting" data.

Hello,
I have a multistart optimization code that generates initial parameter guesses `initialps` as you can see below and later used every row of them to solve a new optimization problem.
