I agree with most of the posts in this thread. IMO, it's completely pointless to force a single return when many would simplify the code. But I have a professor that enforces the single return rule on all of his assignments. I've mentioned to him that I think the rule is absurd (it's a small...
What happened to self ownership? Is it not vain to assume that your view that investment in something is insane must be the correct view? By what objective reasoning could you justify subjecting everyone of the opposing view to some arbitrary standard to act on their view?
Also, I've reduced it to a system of very complex 2nd order noncoupled ODEs, but that doesn't seem to help in solving it. Mathematica can't solve it either. I'm almost convinced it isn't solvable. So it seems the only way to explore it is with numerical methods.
By a fortuitous mistake in copy/pasting, I happened across this system. It exhibits very chaotic behavior for some initial values and spiral-like shapes for others. (About a 70%/30% split, respectively.)
x'=cosy+sint
y'=sinx+cost
Here's an album of it plotted from t=0 to 1000. The titles of...
To what extent? I mean, I can say they found some cool way of saying that the max clique of graphs with a certain type of generator is equal to the max clique of a specific subgraph plus some constant. (I know about the generator and how to construct the subgraph, but I don't want to do into...
I've been given the opportunity to write programs for two different professors working on separate papers (one math, one physics), and when published they say they will list me as a coauthor. With the first, I sort of resisted a little, because I don't see the amount of work I did as really...
You should look into peercoin. It's one of many cryptos that have a hybrid proof of work and proof of stake minting scheme. The idea is that mining will generate initial amounts and when it losses profitability, then users will generate coins using proof of stake. Proof of stake works like...
Overstock.com plans to begin accepting BTC in 2014. http://www.forbes.com/sites/amitchowdhry/2013/12/21/overstock-com-is-going-to-accept-bitcoin-in-2014/
Here's to hoping Amazon will follow. That'll cause a spike like never before.
That is where most of the trading comes from. I mean, look at the volume (http://bitcoinwisdom.com/markets/btce/btcusd). Surely drug dealers and buyers aren't buying and selling BTC at around 5 transactions per minute. And at the exchange I frequent, there's consistently over 5,000 people on...
On Silk Road, transactions where hedged. As in, if you sold your drugs for $50 worth of BTC, you get $50 worth of BTC at the end of the transaction. (There was significant delay between the sell and the end of the transaction because SR had an escrow system.) I don't know how all the smaller...
On this year's Virginia Tech test there was a problem to prove:
\frac{x}{1+x^2}+\frac{y}{1+y^2}+\frac{z}{1+z^2}\leq \frac{3\sqrt{3}}{2}
when
x+y+z=xyz
So my approach was to consider the function, f, where
f(x, y, z)=\frac{x}{1+x^2}+\frac{y}{1+y^2}+\frac{z}{1+z^2}
then restrict f to the...
It may be impossible. I was under the impression that phones are designed in such weird ways to try to pack as much stuff into the given volume as possible. But, that could just as possibly be an excuse for not having replaceable/upgradable parts and thus forcing new purchases. Idk. If you like...
I went with the abs value one because, by nature of the fact they're all random, there are going to be a lot of bad solutions. So I thought a metric which doesn't underestimate their badness would be better. Thanks.
