Hi Kish, Well, you get access to the master space: remember the master() function is called on the _master_ space. That should be sufficient, or?

Am I correct in thinking that the restart search facilities do not provide any way of passing extra current information from the search back to the master() (for DFS; I guess I can (ab)use the constrain() function in my case, as what I want to pass back is a constraint, by changing the DFS search to BAB)? Naively (because I don't know the details of Gecode), it seems to me that providing the user with access to the master space during the search will allow a simple way of passing information to the master space. I can see that being useful if the user want to do things that depends on the state of the search when restarting a search/finding a new solution. > The second option is more meaningful: I think restricting restart to a > single solution does not hurt. I am a little reluctant to do this, as this does not fit that well with how I intend to provide the functionality in ECLiPSe, as I want to add restart and no-goods as extra options to gfd's search routine, i.e. not as different search methods.
