Hi Dan, you can add a dummy variable and minimize/maximize that subject tof(x) > m' and your original constraints. There may be better way of doing that from a computational point of view, but this one will work.
Good luck! Oscar Gustafsoon On Wed, 13 Jun 2007, Dan Tulk wrote:
Hi, Is there a way to get the integer or intopt solver routines to stop when the objective function has reached a certain value? The problem I'm trying to solve is 'find any set of column values that satisfy f(x) > m' where f(x) is the objective function and m is a minimum acceptable value for f(x). I would like to take the objective value found by the simplex solver, subtract a tolerance value from it and use that as the minimum for integer optimisation. I hope to reduce the number of iterations required by doing this Thanks Dan #32; Looking for earth-friendly autos? Browse Top Cars by "Green Rating" at Yahoo! Autos' Green Center.
