Accuracy of integration as target

[jonas-eschle]

The problem

We would like to integrate a function for zfit that integrates a (blackbox) function up to a certain accuracy. So we are not interested in the number of dimensions but would like the algorithm to continue until the accuracy is reached (or maybe a max_iter value). Is that too much black-magic? Or what do you think?

Proposed solution

So far I am not quite sure on the internals and maybe it's also worth to have a new high level function for this logic.

Are you available/want to contribute?

Yes
