optim with specific constraints on possible values
...on "optim" both
without and with constraints from the candidate values (of course the
latter is fast and fine with me), but I am wondering whether there is
kind of optim-function which optimize using only a series of values to
give as additional arguments. Just inventing, something like:
possible1 <- 10^seq(-3,3,0.5)
possible2 <- 10^seq(-3,3,0.5)
...
possible13 <- 10^seq(-3,3,0.5)
new.optim(par=rep(median(possible1), 13),
fn=my.object.function,
from=cbind(possible1, possible2,..., possible13))
Instead of just:
optim(par=rep(median(possible1), 13),
fn=m...
