They played 20,000 hands each.

It was in mirrored play. So player A and B got one set of hands that they played against the computer; and C and D then got the computers hands and the computer got the same cards as A and B.

This greatly reduced the variance in outcome.

They were playing with 200 deep stacks (20,000$, with blinds of 50/100). So the humans were up by 31 buyins; or an average of about 8 buyins. Certainly not a huge margin of victory for that many hands.

Comment: Purpose of the fines (Score 1) 760

If the fines purpose is to be a deterent, then the fine must be sufficient to result in a deterent effect.

If the fine is meant to compensate the public for the harm caused, then the fine should be adequate to cover the cost of the harm relative to frequency of individuals being caught.

If the fine is meant to cover the costs of enforcement, then the distribution of the fine makes sense to have it be on ability to pay.

You've confused statutory with effective rate.

The US has one of the lowest effective rates (how much the corporation actually pays after deductions, etc.), but one of the highest statutory rates (the worst theoretical possible rate that a corporation would pay if it had zero deductions and enormous profits).

My theory is that these are inducements to keep the 'double irish' and 'dutch sandwich' tax dodges available. It seems highly unlikely that Ireland and Netherlands, the two countries that have Allowed apple to avoid hundreds of billions in taxes, and which have suggested that they might change these tax practices, have suddenly become recipients of major investments.

Consumption taxes are relatively easy to evade.

Also the benefit from public tax expenditures isn't proportional to consumption, it is proportional to net worth.

Bill Gates benefits enormously from public education and public funding of universities. He benefits enormously from international trade negotiations and the military keeping international trade relations stable.

Comment: R is not an emerging star (Score 1) 143

R has been around for a long time and has long been a standard.

Pythons sklearn is indeed an 'emerging star'.

Personally I use both.

Also have a look at some of the many stand alone tools vowpal wabbit (blazingly fast for regression learning, scales to ridiculous amounts of data) is superb, as is sofia-ml (for clustering, again scales quite well)

I tie them all together in python, since there are python bindings for R, and you can use pythons 'Subprocess' module to pipe commands and data for commandline tools that don't have python bindings.

There are other useful tools as well - I use Weka for some of my initial visualization and when I'm feeling lazy and want a quick result.

The ban has nothing to do with 'Cold War tensions' it is because Cuban immigrants to Florida hate Castro for the property that he nationalized - and pissing off those voters risk losing Florida in federal elections (and thus losing the Presidential election). Thus draconian prohibitions related to Cuba stay in place.

"There is not a fixed number of jobs in an economy."

There is demand elasticity for labor, but it is not related to availability of labor it is related to demand for goods and services, not availability of labor. The demand for labor is essentially fixed or decreasing without some sort of driver for demand. Immigration can be a source of demand, but it isn't necessarily a source of demand. Since most immigrants send much of their income to their home country they tend to be a net reduction in demand.

The reason unemployment is correlated to immigration is that countries relax immigration requirements when there is a shortage of labor.

The solution of this problem is trivial and is left as an exercise for the reader.
