[SciPy-User] Why does scipy.integrate.odeint still provide a result even after "repeated convergence failures"?

[Brian Merchant]

Hi Warren,

Just an update: I was able to "zero" in on the portion of the model that
causes the issue (I set the ode function to just return 0 for every other
variable, except the one that causes issues).

I can't find an error in the Python code responsible for calculating the
derivative for that variable (I stepped through it, it simply implements a
Hill equation: http://en.wikipedia.org/wiki/Hill_equation_%28biochemistry%29),
and the results provided by odeint in the end don't  seem *obviously*
out-of-whack.

Brian
