WARNING : Capacity of array S in DIRDoubleInsert reached. Increase maxdiv. #3

Closed tinutjoy closed 6 years ago

tinutjoy commented 6 years ago

I am getting this warning " WARNING : Capacity of array S in DIRDoubleInsert reached. Increase maxdiv. This means that there are a lot of hyperrectangles with the same function value at the center. We suggest to use our modification instead (Jones = 1)". What is the modification algo,? How can I use it?

Thanks, Tinu

Hi Tinu, You should be able to change the algorithm that is used by setting the algmethod keyword argument to 1. I do not know the underlying Fortran code enough to be able to say what precisely is causing this warning. Feel free to take a look yourself at the source code in the src directory.

HTH, Andreas

Hi Andrea,

I will check it. I am closing the issue. Thank you.

Cheers, Tinu
