发帖数: 322 | 1 There is a command called Bintprog in Matlab. But it seems
it does not support user-defined objective function. I mean
the ojbective function required in its form is just a
coefficients vector. Other optimization commands in Matlab
such as fmincon all support user-defind obj. ftn. I have a
kind of complex objective function and would like to define
it as a separate function. Anyone knows how to handle this? |

le to solve problems with non-linear ojective... What's your objective funct
ion anyway?

发帖数: 322 | 3 it is highly nonlinear and need to be described by a separate
function. maybe I have to resort to other more powerful solver. Anybody know
s other BIP solver i can try? Thanks a bunch!

a piece of cake for it. There is a link for it with AMPL input. Or you can c
ontact Sven Leyffer (he is a nice guy) for help.
