I have a complicated problem to solve in Mathematica.

a=Sum[Integrate[.....,{},{},{}],{}] ;(*The integral is over three

This yields an error that 2000 is not a machine sized real number in the

range $MinPrecision(0 in my case) and $MaxPrecision(1x10^6 in my case).

I have even tried MaxPoints->($MinPrecision+$MaxPrecision)/2 ! Had I not

been in a hurry, I would have probably found this amusing.

The usual adaptive recursive algorithm for NIntegrate takes too long and

I want Mathematica to give me an approximate answer by using Monte Carlo

(or so the Mathematica book indicates) by using MaxPoints.

Any ideas ?

With regards,
Madhusudan Singh.
