Education index?

The increase in the index slows down gradually and slows even more at higher levels.

The message is in fact:
Don't go in there. It makes no sense. The advantages do not weigh against the increasing cost.

in other words, put simply, DONT GO SPENDING MORE THAN YOUR COUNTRY CAN AFFORD..if a=b which equals a value of c, keep it real it makes no sense, the advantages do not weigh against the increasing COSTS!

Might be?...

Here's what I'm thinking now.

While the docs says: "It is computed every month by taking the lowest of the three partial indexes, adding to it 4 times the current education index and dividing the result by 5."
Edu_t = (min{A_t,B_t,C_t} + 4*Edu_t)/5)

It probably means something like this: "It is computed every month by taking the lowest of the three partial indexes, multiplying it by 4, adding the previous education index and dividing the result by 5."
Edu_t = (4*min{A_t,B_t,C_t} + Edu_(t-1))/5)

That last one is in line with what you wrote for the Health Index.

I have a hard time believing those are the equations being used, as they correct much faster than what I think is going on. But this would be compatible if the function that gives X, the value to which the index is converging to and depends on hospitals/schools,

By the way, the closer the coefficient is to 1, for the set of information of time t, the faster is the pace of convergence. So, no, 5/6 is actually slightly faster than 4/5. Take this example:

Y_t = aX_t + bY_t-1

As a + b = 1, if a is 1, then only one period is needed to converge to it's new value. If a is 0, it doesn't converge to it's new value, it stays at the previous one indefinitely. a is giving the percentage at which the gap is being closed consecutively.

If you are going to change that, remember that the sum of the coefficients needs to be 1, in order to have a nice behaviour. So, that "5x" better become "4x".

I bet it's a shoe coloured with all kinds of theorems on it.

So... Today I had a little experiment to put my assumptions and the information the GameMaster provided to the test. Guess what? I do have a nice feel after all.

I measured how much current information weighs on the education index, and it came up as being 1/5. It's amusing, because I was excepting 4/5. Seems like the information provided on this thread was switched, so that "4/5 is a bit faster" thing now makes sense. He just wrote the equation wrong. Its' actually:
Y = (X + 4*Y_(t-1))/5

Not so me as I am babbling, it is that not even once the index was reported correctly. I've corrected that.

Great, I'm sure everyones so much more the wiser for that.

If any people playing out there are wondering, the edu index will follow the lowest of the 3 individual indexes. Simples, no?
