Getting higher calls for fitting

Hi,

So I am pretty new to fitting, how would you increase the number of calls do when fitting custom functions, I know a call is a number of times it calls the actual function and I have an intuition that higher the call number the greater the accuracy but how would you “get” higher calls to improve accuracy?

Thanks

I guess @moneta can help you.

Hi,

Increasing the number of calls it will not do anything if you are using already an high number, This because the minimisation procedure stops normally before when reached a low enough tolerance.
You could then decrease the tolerance value, however it will not also help much because in general your accuracy will be limited by numerical error computation of evaluating the user provided function
