Re: negative transition probability

Stop blaming Feynman all the time :D
Paul started it I think! (Dirac)
So, we blame Paul (D)?

Re: The Final Frontier: negative probability in Machine Learning

NP is a thorny issue and it depends who you talk to engineers; don't believe in it, but APL supports it physicists believe religiously in it; just change reality if necessary mathematicians: don't care ML : of course Amen why u also need AI. AI can be used to detect fake news!   and fake probabilit...

Here we show that this effect is mathematically equivalent to the appearance of classically forbidden probability flux" 2019: "We also demonstrate that Feynman’s negative “probabilities” provide for a more reliabl...

"Who was the copy-editor?" not sure, could it have been Paul?

I am thinking of making a C# and a Python 3rd version....but mostly thinking about it...

it was translated by Shanghai stock exchange, I think they are better translators into Chinese than P. Wilmott (but what do i know, he used to have some hidden talents, cheese making etc.. )

Re: Random quotes

" AFAIR C# is even faster than C++ in some cases (JIT)."
Confirmed in our testing (well naturally also depends on how code is written), I was first shocked !

also DNA is awesome together with C#

Re: Random quotes

Unless one is just a sucker for C++, it needs to be considered that the C++ code development time is several times longer than in the case of Python. Probably until your Python code base reaches the tipping point and then get Big Ball of Muds. C# is 3 times more productive than C++. yes C# is the T...
