 Hello all,

Trying to implement GARCH(1,1) with ASP.NET <http://asp.net/> and
VB.NET<http://vb.net/>.
It involves optimization of a three-variate function with some constraints.
Learned from Wilmott.com <http://wilmott.com/> that R might be able to do it
but have no idea how.  Could anyone help me out please.  Thanks in advance.

Additional info:
1. Tried calling Excel Solver from within my web application - it works fine
except that Excel.exe won't go away from task manager although the Quit()
method has been used;
2. Also tried running (Process.Start) a separate console application that
calls Excel Solver from the code, getting error message: The application
failed to initialize properly (0xc0000142).
Any thought of an alternative?

Best wishes,
Pat
