Could anyone tell me how I can find the set of non-active constraints in a model in cplex?
I have a Vehicle Routing Problem model with two types of constraints, let call them type "passage" and type "demands". Associated with each node on my graph, there is a constraint of type passage, defining the number of visits to the node. The right hand side value of these constraints is one (i.e. >=1 ; each node should be visited "at least" once). What I need now is to find the set of nodes which have been visited more than once ( >1 ; non-active constraints of type "passage").
Is there any direct way to obtain this set or I have to write a new method?
Thanks in advance for you help.
