Hi Andrew,
Ok. Let me put this question in a more generic fashion so that its
appropriate to this group.
I have a Integer programming formulation which has a variable u{i} where i
varies from 1 to n and another variable V. Each u{i} can only take binary
values 0 or 1 and same for the variable V.

In my optimization work, I almost always use the
API of a solver instead of a modeling language.
The reason is that I usually want to solve another
problem related to the first and its solution.
Absent a reliable mechanism for converting variable
names to variable indices this can be
Hello world:
I need information about papers of mathematical programming and
operation research where they use glpk, to argue in my master thesis
(relations between integer programming problems and its polyhedron)
the use of glpk and not only cplex.
In other words, for what is possible use glpk
Maybe the solution is to develop some sort of plug-in API or framework
that would allow for the programming type extensions but with access to
the underlying data structures in MathProg.
