Hello, I've been trying to implement this LNS engine. The idea is that once a solution is found, some part of this solution is destroyed to be re-inserted in some different way. I don't really understand how this can be done though. Currently I build a completely new model constraining the variables that are not destroyed to take the values they had in the previous solution. Is there some better way to "unassign" a variable though?
Many thanks, Joan
