Hello, I'm new to julia; I discovered it when I posted in the python pulp-or google group about generating large LP models.
I currently use AMPL for model generation, but I'd like to switch to an open-source alternative. I first went to pulp-or because I'm familiar with python, but it's too slow; julia looks promising, but I'm concerned that since I don't have a solid grasp of the language I might code the constraints very inefficiently. The LP models I'm generating are about 1.5Gb as .lp files and take ~20 minutes to generate on an 8Gb machine using AMPL. It would help me get started if someone here could translate a piece of my AMPL code to julia. I think I can translate the whole model if I have an example to compare against. Anyone here interested? It would be about 10 lines of AMPL code, describing a variable defined by two derived sets. Regards, Andrew
