Questions on Case Study student attrition

Re: Advanced Predictive Modeling Using SAS 9.4

I would be grateful if someone could clarify the following points on the solution presented on the final Case Study for this module (references/times refers to the videos presenting the template solution):

Q1. (Video "Advanced Model", time 9:00) Would it be possible to have a copy of the code used for the simulations to determine the optimal paramters for the Random Forest model?
Q2. (Video "Advanced Model", time 10:42) Would it be possible to clarify what the Harold's approach is? The presented solution mentions that Harold's approach was described in the neural network course but I cannot find it in the course text for "Neural Network Modelling"
