Hi there,

For those who use R to solve mixed integer linear program (MILP), what are some recommended packages?

From my googling and cran taskview I can see a few: ompr+roi, lpsymphony etc.

But I want to get some advice from people who actually does this stuff in R. What's your latest recommendation?

I've recommended ompr to couple of people (but never used it myself) and they seemed to be able to solve their problems with it.
