When I read the documentation, it appears
that the AMPL like abilities in GLPK do not include the for-loop control structures. In particular, there is very little you can
do after the “solve” command (basically you can use “display”
and “print”, but there is no facility for examining the solution
and rerunning the linear or integer program). In “real” applications of
linear and integer programming, I almost always need
some post-solution control due to either: (1) Decomposition techniques (such as
column generation) (2) Having the linear program only able to
approximate the real-world problem. In
this case, the solutions need to be analyzed and the linear program needs to be
adjusted several times before an acceptable solution that fits the “real-world”
constraints is obtained. So my number #1 wish for Andrew is to add
in the same type (or better) post-solution control that AMPL has. -Marc Meketon From:
