Happiness calculation #3

Open bruceravel opened 13 years ago

bruceravel commented 13 years ago

Shelly Kelly said: I'm using demeter to fit cu foil and got a happiness factor of 100/100. While my model is of course perfect, (hum)... I think it should be harder to get 100/100. For example, one of my debye temps is 200 +/- 100. Now that can not be true happiness.'

A few comments on this:

There are prefernces for tuning the happiness
In the future, I want to include a penalty GDS parameter whose evaluation gets subtracted from the happiness
It would be useful for demeter to have access to a parameter's uncertainty in math epxressions or internal calculations
In any case, a suggestion for an algorithm for computing a penalty to the happiness is more useful than a complaint about the calculation
