I’d like to optimize parameters in the MOL example shown here with an RMSD cost function to minimize. Following a WIP example here to build the OptimizationFunction, I have the following, but the results come back predicting the max of the bounded range. using ModelingToolkit, MethodOfLines, Ordin…
