Where can I find a description of the minimisation routines used by the neural network predictive controller?

I'm using the neural network predictive controller in simulink. There are five different options for the minimization routine but I can't seem to find out what they actually are. i.e what are csrchcha, csrchbac, csrchhyb, csrchbre and csrchcha?

In the neural network toolbox users guide it says:

 " The linear minimization routines are slight modifications of those discussed in “Multilayer Neural Networks and Backpropagation Training” on page 3-2."

I've tried looking there but none of the training algorithms seem to correspond with the names given in the neural network predictive controller block.

I'm using the NNPC too in simulink and I need some help please, where can I find a description of the search parameter ?

Can I use a script in stead of the NNPC block on simulink ? does it work with MIMO system ?

Hi Joshua,

I hope the following links help answer your question:

srchbac

srchbre

srchhyb

srchcha

These are the routines referred to in the documentation which are slightly modified.
