Dear Yan:

The page ?optim says

  If a function to generate a new candidate point is given,
  method ‘"SANN"’ can also be used to solve combinatorial
  optimization problems.

If you have your specific function to generate a new point,
this function may apply the required restrictions.

Hope this helps.
