Hi, Andy directed me here. 

PyMinuit handles multiple parameters easily - but only if the definition of the
function to minimize is fixed. E.g. a hardcoded f(x,y) works perfectly fine, so 
in our code we have to dynamically generate a string which represents a 
functions
definition of N (N can be anything greater than 0) parameters that is later 
used via
the 'exec' statement to actually define the function PyMinuit is considered to 
optimize.
