====== Minimizing Root Mean Squared Difference with 5 point bracketing (bi-section variant) ======
A typical calibration problem is to get the model results to track on something while tweaking a variable.  The approach described here attempts to minimize the difference over time between the model variable and some given tracking variable.

Here is the code for the .t file for the feed back view.  The example implementation was to change the unitTA variable such that the difference between the model calculated space conditioning energy use and the energy use left over from the Stats Can total energy use minus the non-space conditioning energy use is minimized.

Instructions on how to customize the file for your situation is right in the top of the file.

===== Example code - simple =====

<file>
! ** This is a generic bracketing feedback view that does a divide and conquer approach **
! ** REQUIREMENTS:**
! ** 		It requires a min and max starting value which bound the problem **
! ** ALGORITHM:**
! ** 		1. It divides the solution space into 5 evaluation positions, runs the model at each place and **
! ** 		chooses the position that minimizes the root mean squared difference between the model estimate **
! ** 		and the target **
! ** 		2. It then reduces the step size in half, chooses 5 more points centered on the best result from **
! **    the last evaluation and then runs the model (as needed) to get the result at these 5 new positions**
! ** 		3. Repeats the process of finding the min of the 5 points and sets up 5 more points until **
! ** 		the step size as a ratio of the best guess is less than the feedback view tolerance **
! ** HOW TO CUSTOMIZE FOR YOUR PROBLEM **
