Say you have a mathematical program written in algebraic language such
as MPL, GAMS, etc.
Can someone refere me to a link that shows a Mathematical Program
written in JAVA?

I have a variable binary vector lets say U[5]. I have a variable
integer vector lets say S[5]. The constraint i am trying to formulate
is as follows:
sum over all j ----> U[j]*S[j] <= C (some fixed integer) .

I have a variable vector A and B (both binary) a certain length.
I want to define a new vector C[j] = min(A[j],B[j])
I want to implement this condition in Cplex. Is the following logic
correct:

I have an LP problem which is solved using the column generation
method. This results in the optimal master problem (RMP):
min F(x)  s.t.
A x >= b

I have the following assignment problem for which i have already
formulated an integer linear program. I was wondering if there is a
known algorithm for solving the problem. A reduced version of the
problem is as follows:

The data associated with linear programming is stored and transported
electronically in files.  For professionals handling these materials,
e.g. analysts and programmers, it can be very helpful to deal with
standard file structures, as proposed here: http://www.iging ...
