|WikiProject Game theory||(Rated Start-class, Mid-importance)|
I rewrote most of this page and added a lot of content, as I had promised long ago. I also added recent two references where the general theory can be found. The article could benefit from a concrete example of an application of the equation, perhaps from both biology and economics. Marc Harper 19:16, 5 February 2007 (UTC)
- I made some more additions -- I would have done it with the first round, but I had to look up the references. (Forgot to log-in for some of them...) Marc Harper 23:43, 5 February 2007 (UTC)

- What do you mean? They can be essentially anything that you want, though the most common form is f_i(x) = (Ax)_i (ith entry of the matrix product) so that the fitness function as a vector f(x) = [f_1,..., f_n] = Ax . If you want the differential equation to have nice properties the f_i should be relatively nice, but the need only be integrable to solve the equation (in principle).
If you don't know the relationship between the Price equation and the replicator equation, read the reference "Unifying Evolutionary Dynamics". Do not delete content because you think it is incorrect! —Preceding unsigned comment added by 184.108.40.206 (talk) 19:32, 3 December 2009 (UTC)
