virtual

Minimize the function.

Parameters

maxfcn	: max number of function calls (if = 0) default is used which is set to 200 + 100 * npar + 5 * npar**2
tolerance	: value used for terminating iteration procedure. For example, MIGRAD will stop iterating when edm (expected distance from minimum) will be: edm < tolerance * 10**-3 Default value of tolerance used is 0.1
