I believe Newton said, "If I have seen further it is by standing on the shoulders of giants.", not, "I have rediscovered everything in a slightly different way because no-one gave me more than a vague method to go on"

It is no bad thing to have several independent implementations of an algorithm. If there is a problem with one, then the others are likely to show that there is a problem. However, without open source code, all you can do is say, "Mmm, something's wrong somewhere" and write another version. You may end up with several papers that agree and one that doesn't, but you still can't draw any conclusions without looking at the code. Ultimately, you get a situation where everyone has to repeat the same work and see what they get, when what they should be doing is poring over the original soources and discussing which bits could/should have been implemented differently and how that affects the result.

The code is part of the method. If you can't show us the code, don't expect me to believe your 'results'. That is science.

Newton also said, "If others would think as hard as I did, then they would get similar results." This seems to be part of the attitude OP is taking, that if others want his best, most unique results, they should arrive at them independently. But then when someone did that with Newton (Leibniz), the resulting fallout "redounded to the discredit of all concerned." (Here is a nice summary of the beef: http://www.ams.org/notices/200905/rtx090500602p.pdf)

I once looked and could not find any evidence that Newton said that. Since the quote is designed to sound good to modern ears, the attribution to Newton is probably bogus.
