I found this reference, so 80 valuation, Be wanted upwards of 200, “In 1996, Apple Computer decided to abandon Copland, the project to rewrite and modernize the Macintosh operating system. BeOS had many of the features Apple sought, and around Christmas time they offered to buy Be for $120 million, later raising their bid to $200 million. However, despite estimates of Be's total worth at approximately $80 million,[citation needed] Gassée held out for $275 million, and Apple balked. In a surprise move, Apple went on to purchase NeXT, the company their former co-founder Steve Jobs had earlier left Apple to found, for $429 million, with the high price justified by Apple getting Jobs and his NeXT engineers in tow. NeXTSTEP was used as the basis for their new operating system, Mac OS X.”
I have about 5 years of experience in MiniZinc solving scheduling problems but sadly all that code is locked behind closed doors never to be open sourced. I would love put together some fully worked constraint programming examples complete with containerisation / visualisation/ modeling etc but the barrier to doing so is finding problems that are actually worth solving and have open source data to work on.
As for the "mathematical equations" referred to by a parent, we're talking linear algebraic equations with perhaps a 2nd order term thrown in for quadratic models. I think these should be within the grasp of someone who wants to delve into the topic, and if not perhaps it's a good place to start dig deeper.
edited to be less of a prick.
