People have different risk exposures and different risk appetites. If you're a corn farmer then your entire livelihood is tied to the price of corn. You're willing to give up expected value to reduce risk by selling futures and there are others who are less exposed to corn prices who are willing to take the other side of that trade.
FWIW for my comment I essentially used your code and cleaned up compiler-generated imperative code.
So yes it used the fact that it only recursed to n-1 but did not use any optimizations related to booleans. And looking at other examples can see general principles. You store a data structure for each function which acts as a cache. For example, suppose you said even(0) = True, even(1) = False, and even(n) = even(n - 2), then one way would to unroll it would be to use a size 2 ring buffer as a cache.
I was there until the end. It was definitely fading into obscurity but still had >50% of peak numbers. And we were switching to C++ in the last year or so.
There is actually already a Scheme interpreter implemented in Rust (https://github.com/mattwparas/steel) which has the same name for the exact reasons you stated.
There is a professor who was at Wisconsin, Charles Manski, who developed partial identification, which uses tons of these decompositions.
Idea is let's say you have a binary survey question where 80% respond and 90% of them respond "yes". What can we say about population "yes" rate (assume sample size is huge for simplicity)?
Then 0 <= P(Yes | no response) <= 1, so 0.72 <= P(Yes) <= 0.92. This example is somewhat trivial but it's a useful technique for showing exactly how your assumptions map to inferences.
Interesting, hadn't heard of that one before. With some digging this appears to be the first case where they have ever charged someone for "shadow trading" like this. And it is still making its way through the courts. Definitely will be following that.
This is another situation where I am literally dumbfounded at the actions of the indicted. How are you smart enough to know what options are and how to buy them but stupid enough to think that you won't get caught making such a blatant trade?
It's like these people think they're the first ones to ever come up with the idea of trading on privileged information so there's no way they'll get caught.
Reminds me of the Kairos retreats popular in Catholic high schools. I went to one and it was pretty intense and not in a forced way. Basically 4 day group therapy.
It is still a thing, at least in Brazil afaik. My cousin went to one these retreats the other day, he tried to convince me to go with him but I don't like those. He said it was really intense and very "close to god".
Most trades through a brokerage don't make it on an exchange. They're internalized by a wholesaler like Citadel Securities. Which is the reason for the question.
