Indeed so although its performance is not so good. There are a range of
algorithms implemented in other languages like scipy for Python and the gnu
C libraries. Code for any of these optimisation algorithms would be useful.

Looking around a bit more it looks like the downhill Simplex  
https://en.wikipedia.org/wiki/Nelder%E2%80%93Mead_method looks quite good
and not too difficult to implement .  For a 2D function it needs 3 initial
points -  I'll give that a go.

Of course the problem with using such functions as you well know is the
inability to pass functions as parameters- I must checkout Curv!
