Hello all I'm trying to use simulated annealing to optimize a function. I know I can use ?optim with method=SANN to do it. However, I'd like to make optim to search for the best solution among a set of possible points in my domain, and not informing a lower and an upper bound to the optmization

[R] discrete simulated annealing

Dear All, I need to use simulated annealing for optimization is there a way to limit the search place to only discrete values? And also exclude certain solutions, e.g. exclude the solutions when all the variables are the same? many thanks Yan __
