It is possible to use martingale probability theory to beat some games
of chance. In a fair game of coin toss, where the odds reach an
equilibrium of 50/50 chain reactions do occur. This can be explained
using martingale probability theory, but in simpler terms it only shows
an example of how order emerges out of chaos.

Example: One player has 3 pennies, and another player has only 1 penny.
A fair coin is tossed every round to determine if a penny is won or
lost for either player. The odds are 3/4 that player A (Who begins with
3 pennies) will win the game. This is entirely different than the
martingale betting strategy, because only 1 penny is bet for each round
of the game.

Because there are 3 ways player A may win, and only one way player B
can win, player A has a concrete advantage. Player B, only wins in the
event that the coin is tossed in his favor 3 times in a row, while
player A can win on the first throw. Or he can win after losing the
first coin toss, or he can win after losing the second coin toss. So
the odds are 75% that he (or she) will win in this game.

Upon further analysis it is possible to calculate the average number of
coin flips before player A is likely to win. The equation k(n-k) works
for perfectly fair games according to martingale probability theory to
solve this problem. In this case 3(4-3) solves the problem, so on
average it takes 3 coin flips for player A to win.

To show that chain reactions occur you only have to move from the
probability of winning the first game, and multiply it by the
probabilities of winning the following games. For example, if 3 pennies
are used to play this game in an attempt to win one penny, the odds are
3/4. And once that penny is collected there is now a 4/5th chance of
winning another penny.

So statistics tells us that there is a (3/4) * (4/5) * (5/6) * (7/8) *
(8/9) * (9/10) = 30% chance of the 3 pennies growing into a pile of 10.

But in repeatable tests you will find that on average there is not a
net win or loss in this game. If there is a 75% chance of winning 1
penny, and a 25% chance of losing 3. The two odds cancel each other
out, to create an equilibrium in 50/50 games.

And at the same time we can see that despite the fact that the initial
value of coins reaches an equilibrium when the pattern is extended to
any length, we can show a concrete advantage to beginning with 3
pennies, instead of beginning with one.

In the last example player A had a 30% chance of winning 7 pennies, and
totaling 10 in all. If we started with only one penny then player A
would just have to total 8 pennies in order to earn 7. So lets look at
the math:

(1/2) * (2/3) * (3/4) * (4/5) * (5/6) * (6/7) * (7/8) = 12.5%

So we can cleary see that even though winning 7 pennies has the same
expected value as losing 1 penny. Outside of repeatable tests the odds
of earning 7 pennies is clearly higher if you begin with 3.

I can also explain the laws of nature with these prinicples. If we
look at the equation for gravity on earth, which accelerates at 9.8 m/s
we can derive an acceptable answer from the earlier equations. The
gravity equation I am using is sqrt(2*n/9.8).

In this example we are dropping a ball from 4.9 meters, and you can see
it takes one second to land.

t = sqrt( ( 2(4.9 m) ) / ( 9.8 m/s^2 ) ) = 1 s

So here is my gravity theory. We are using the quadratic formula to
solve: 2*n/9.8 = k(n-k) , for k. (The formula k(n-k) finds the average
number of coin flips).

k=(1/14) (7n +- sqrt(49 n^2 - 40 n)).


So now an example...


We are dropping a ball from 10 meters above the ground. So we plug 10
meters into n to solve for k.


k=(1/14) (7n +- sqrt(49 n^2 - 40 n))
k=9.791574237


My question to calculate the average number of coin flips in my game is

k(n-k), so we plug in k & n:


k*(10-k) = 2.040816327 = average number of coin flips


Now we take the square root of the average number of flips to get the
actual time it takes to land:


sqrt(avg flips) = 1.428571429 = number of seconds to land.


Now finally to factor in a problem with my equation we say that if k is
9.791574327, that means our large gravity pile is that many pennies.
And our small gravity pile is exactly 0.208425673 pennies!

Seconds, meters, and the mass of the Earth are all arbitrary
parameters.

If we had no pinkie fingers, we could just as easily be measuring time
in PixieTicks (64 of them in a Plonk, 32 Plonks in a day). The Earth
could just as easily been 30% larger. The meter then would be 1/16,384
of the distance from the equator to the North Pole.

That would mess up the nice coincidence you've found.

I don't think OP had one, but there were several C things to mention
in the program he posted following all the preceding pointless drivel.

No, it isn't -- but more on that would be off topic.
In a fair game of coin toss, where the odds reach an
equilibrium of 50/50 chain reactions do occur.

In a fair game of coin toss, each toss is completely unrelated to
every other toss that comes before or after it. If your simulation
reveals any correlation, you have merely found a flaw in the
so-called random number generator. This is in fact a classic way of
testing the quality of a pseudorandom number generating algorithm.

The typical rand() implementation is not known for being
particularly good. It's suitable for undemanding casual purposes.

Read the FAQ on random numbers. Read Knuth. Remember that all
pseudorandom generators produce a fixed reproducible sequence, and
meditate upon how that fact relates to whatever you are trying to
test or prove.
