->Based on Olly's extremely good advice, I made changes to Inl2 and Ifb2 by
calculating some complex sub expressions in Init() whhich depend on
constant values. They are a part of the pull requests.
-> I also optimized IneB2 weighting scheme by :-
a.) Simplifying expressions and cancelling out common factors.
b.) Caclulating common sub-expressions in Init()
c.) Tightening the upper bound.
I have opened a pull request for IneB2 too.
-> I am now working on DPH. I think I have some new ideas after discussing
the upper bound optimizations with Olly today.
-> I will also work on timing the automated tests for the old and new code
for each scheme and also profile the new scheme with kcachegrind and
document the output.
