Dear Developers, I find the possibility of GLPK to read and process MathProg models extremely helpful. Thanks a lot for creating the translator! In my view, MathProg is usually a much more convenient form to specify a linear program than directly filling the constraint matrix with numbers. However, I have an application that has to solve the same model many times with different specifications of the sets and the parameters of the MathProg model. In this application, creating every time a new instance via the MathProg translator seems rather slow in terms of computing speed. I wondered whether it would be possible to add a function to the MathProg translator that can create from the internal model representation of a given MathProg model some C code snippet. The snippet would be a C (or C++) function that takes sets and parameters as vector input and returns the constraint matrix, bounds and objective coefficients of the linear program as output. I could imagine that this could be quite useful, since one could specify the logic of the problem in the convenient MathProg form, but still can embed in the application fast code to generate the linear programs. However, I have no clue whether that is possible or hard it would be to create such a snippet generator.
