I have the following question on how to define a set:

E^((1) ) (p_0,p_d )={k_u∈E_1 (p_0,p_d )|(p_0,p_d )∈Q^((1)) } Where Q^((1))={(p_0,p_d )∈Q:0

How to define E^((1) ) (p_0,p_d ) / Q^((1)) and E_1 (p_0,p_d )?

The following is the code: int Resources = ...; // Number of Stations to select; range Stations = 1..Resources; float charge_stations[Stations];

range Interchanges = 1..Resources; // Number of Interchanges to be covered; // Define Traffic Flow sets, distance and related binary variable tuple flow {int i; int j;} setof(flow) Flows = {<i,j> | ordered i,j in Interchanges}; float distance_flow[Flows] = ...;

tuple stations { float charge_stations; }

tuple traffic_flow { float distance_flow; } float Budget; float Safety_distance;

dvar int Build[Stations]; dvar boolean FlowsInSet1[Flows]; dvar boolean Cover[<i,j> in Flows];

Thanks a lot!
