Are there any packages that do non-linear integer otimization? Looked at lpSolve but i'm pretty sure it only works with linear programming and not non-linear, tried "L-BFGS-B" optim after flooring all my params, works somewhat but seems really inefficient. Anything else I should look at? -- View this message in context: http://r.789695.n4.nabble.com/non-linear-integer-optimization-tp2551409p2551409.html Sent from the R help mailing list archive at Nabble.com.
