integer constraint
Dear R users, I have a question about optimization. Is that possible set a constraint that only integer values are allowed for the optim in the R base and some other optimizers such as psoptim in the package pso? For instance, my lower bound is 0 and upper bound is 100 and I only want integer from 0 to 100. Is this possible? Thank you very much for any help in advance. with kind regards, Chun
