Expansion Algorithm: Acceleration Over Time

[amaruq]

What is the algorithm for expansion acceleration (here) over time?
I have had no luck finding this, maybe I was looking in the wrong place in the library.

It's unclear to me what you are asking. Do you mean you want an equation that gives the acceleration of the expansion as a function of time? If so, that is just the Friedmann equations: http://en.wikipedia.org/wiki/Friedmann_equations

yes that's it. Thank you.
