CarbonAbsorptionHandler model about kyoto HOT 7 CLOSED

This makes CarbonAbsorbtionHandler very similar in CarbonReductionHandler.

I have however discovered another problem with it.
Imagine a very unrealistic (but theoretically correct) situation:

Country A has area 100 and 100% of it is arable
Country B has area 100000 and 100% of it is arable

Now country A can invest in carbon absorption and changes 1% of its arable land into forest. It cost it, let's say $1000. It gives them 1*X in tonnes of carbon per year added to Carbon Absorption. (X is how much carbon per year is absorbed by 1 nit of forest)

Country B invests in carbon absorption and changes its 1% arable land into forest. It costs exactly the same - $1000 as the price depends on the percentage change. It however gives them 1000*X in tonnes of carbon per year in Carbon Absorption.

I think it is not very real, but acceptable for our model. What do you think?

Same issue applies to carbon reduction.

That's not what I meant.

My idea is that only price of a single block of forest depends on the percentage of area that is free (arable / total). Hence, using your example, planting trees on 1% of the area would cost different amounts. While the average price for a single block in the transaction (which we can calculate and use easily if it is a linear function) would be the same for both countries, Country B would have to pay for 1000 times more blocks than country A. Which is sensible, as it would get 1000 times higher absorption boost.

Also, to comment on the function of cost itself: While quadratic is much more realistic, we think that it massively complicates things. Since we have very little time, it seems a better solution to use linear function so that it can work asap, and then, if we have time, do a quadratic function instead.

I think the formula will be realtively simple, I can implement it tomorrow at uni and write a wiki on it. It can be used both in reduction and absorption handlers.

So by the end of tomorrow, I think I'll manage to make the handlers working and hopefuly test them to prove so.

Ok, I have heavily modified the CarbonReductionHandler, including its constants. Will do the same with AbsorptionHandler tomorrow, and will merge group2 which I am working in with dev.

Hence, be prepared that both will seriously change tomorrow early-afternoon, but it should not make much difference for anyone using the handlers, the only difference being that the functions now take doubles instead of longs.

I have discussed the changes with Piotr and I have realized where my last model failed. Piotr's solution, although less mathematically "cool" fixes it, so I totally support what he is doing here.

Done, closing.
