In the last 30 years there have been studies claiming that with very very good methodology, you could cite some of the stuff from the '80s and you wouldn't be incorrect.
And what you suggested isn't at all uncommon in those quality work studies.

A controlled environment of people not changing their diet and lifestyle in a 20 year time span.
There's plenty of studies like that.
There are quality studies where p-values tell that their sample size isn't large enough, but when you do a meta-analysis of studies with same methodology you get a relevantly sized sample.
I do guess you are talking about those "Phd nutrition guys" and yes, they are full of bullshit and aren't scientists, because if you are talking about the real science, your comment is full of disinformation.
Problem is that no one looks at meta-analyses, no one reports about it. WHO has reports that are sometimes half-assed and clearly * put large food industry * neutral.
Just take the newest biggest report on eating processed meat being equivalent to 3-5 cigarettes per day (cancer up by 18%). They did a meta-analysis on 800 articles, and in those articles and conclusions authors clearly state that meat can be substituted by alternatives that do not cause cancer, but WHO decided to skip that and mention that there are health benefits to eating meat (high iron which is not that high compared to plant sources, B12 which of course, cannot be found anywhere except animals and fortified foods).
They do the same thing with milk, supplements etc.
I've noticed this being a good way to maximize credit.
I've been tweaking my Android tablet's code (10" screen), profiling, setting up all of the possible GPU optimizations (whole UI is whenever possible displayed using it) and this is the result.
This is about a one year worth of work but I guess Android engineers don't have time to optimize per device.
You could probably squeeze out the same for any mobile device, although iPhone is probably not that configurable.
“The real cycle you're working on is a cycle called yourself.”
“Like those in the valley behind us, most people stand in sight of the spiritual mountains all their lives and never enter them, being content to listen to others who have been there and thus avoid the hardships.”
These talk a little bit about self-improvement, or that knowledge is not understanding. Telling someone that new relationships aren't going to help, that acquiring new stuff won't help, is just giving them your personal knowledge/wisdom but you can't give them understanding.

many complete proteins exist in their raw unprocessed forms.

Tooling is absolutely great, Atom plugins are very fine, really, it's very enjoyable and it all happened in a single year.
I really do not understand why almost everyone thinks that "network effect" is the best thing Uber has, when it obviously isn't.
This will give them enough competitive data to figure out the live on-line algorithm. And of course, lowering the prices still, but it won't work for those of us who want the routes now, not planned upfront.
Way to go free datasets.
Although it's nice to know that researchers at Uber still haven't figured it out, makes the competition a bit happier.
It's quite funny how a company raises so much money, and then, after you have it you go solve the hard problems, or at least that's how Uber works.
Eventually he ended up being an engineer there.
My experience and rejection also indicated there's something arbitrary random going on in the interview process. Once a recruiter from Google commented my grades with a serious attidute, saying I should keep them as high (I was still a student) and I immediately realised that grades weren't even checked because my grades were horrible (GPA<3, ridiculous bible theology social classes ruined it for me) and if they cared I should get them higher.
I could be an empty shell imitating a human perfectly, all other humans would buy my lack of consciousness, and nothing would be different, from their perspective I exist, from mine, I don't have mine.
How does one know that I really understand something? Maybe I can answer all the questions to convince them?
You take the previous solution, and the current one, the difference of the cost (up or down) and plug it into the formula.
Simulated annealing allows some jumps up and jumps down, hill climbing goes only up.
The problem you know is NP-complete has to be reduced to your Santa problem.
What OP described was mapping from Secret Santa to Hamiltonian circuit, not the other way around.
I've had a bunch of problems reduced to be solvable with approximation algorithms of NP-hard problems, that doesn't make them NP-hard, it's equivalent to solving a problem by reducing it to an NP-complete one with an exponential algorithm.
That's why it's not that simple to prove a problem NP-complete.
It might be that the problem is filled with symmetry and by modifying an algorithm for an NP-complete problem you get a polynomial one.
For example, Vehicle Routing Problem with Time Windows (multiple Hamiltonians with time windows) is considered NP-hard but if your locations had a lot of short time windows you can solve any instance in polynomial time (almost O(n)). But you can also solve it with any VRPTW algorithm (DP, PTAS, heuristics etc.).
The guy who responded too mentioned the "network effect".
I'm quite baffled by what is exactly the problem?
What, you are afraid that your babysitters will decide to dump your platform because one single individual is offering them more money?
What is stopping you from making your logistics work in a way that a preferred babysitter comes every time? Of course, that would make your logistics problem a bit harder, but that is exactly the point I'm making.
Network effect exists because of incapability of the system to create a situation where your workers would make more if they left your service. But, if you allowed the clients to have the same babysitter, same chef, and at the same time have an algorithm that is superior to everything else on the market, yes, the "Uber for Babysitting" idea is a stupid one, an obvious one, but execution is far above a "common guy" startup.
Problem can be defined as pickup and delivery, on the fly, or offline (knowing all of the orders in advance). If you solve the on the fly, you've solved the offline problem. Picking up people, or food, delivering people, or food, problem in its essence ignores the subject and optimizes the pickup/delivery.
