Dennis,
The MO algorithm combines well known mathematical optimization techniques with other customized algorithms, tricks and heuristics that take advantage of the special structure of an MO problem. It is not a simple formula.
Since you are starting development in MO 6.4, my recommendation is that you take advantage of the powerful MO standard settings, and as you progress if there is something specific that you would like to change, then you write back and tell us about it.
Welcome to the wonderful MO world!!
