From: Axel Etzold Date: 2008-05-14T16:40:56+09:00 Subject: Gecoder syntax question Dear all, I have an optimization problem. I need to minimize || A(x-y) || while maximizing ||x-y||, where ||.|| is a norm, x,y are vectors with integer non-negative entries and A is a (at that point fixed) matrix with float/double entries . x is also fixed, so I am looking for vectors y "far from x" that are mapped closely to where x is mapped under the linear mapping induced by the matrix A. How can I declare a matrix with float or double precision entries in Gecoder to formulate the problem ? Thank you very much, Best regards, Axel -- Psssst! Schon vom neuen GMX MultiMessenger geh�rt?
