Hello I am running a program from value intervals for a set of variables. I thought I could use Smolyak to get my intervals adding points as I need them , so instead of running the program for a whole interval I would run only for the most important points. I am new to Smolyak algorithm though, and I can not understand how can i use smolyak.quad(d,k), to solve my problem. Anybody can give me some li...

adapt may "cheat"
...re produced by the gaussq.f function from netlib to calculate the univariate integral then squared it, and the result differ from the adapt number in the 4th or 5th digit. Forcing adapt to use more points doesn't seem to have any effect. We were led to this experiment when we were testing the smolyak cubature in SMOLPACK by Knut Petras, which gave the same number as the squared Legendre.
