W pierwszym kroku pracy solvera zainicjalizowane zostają odpowiednie zmienne i tworzona jest lista skonfigurowanych węzłów:

Storę storę = new Storę ();

NetworkBuilder net = new NetworkBuilder (); List<IntVar> arcList = new ArrayListo 0;

// Generate new map

nodesArrayl nodeMap.getldO ] = net.addNode( ":"+ nodeMap.getld()+")", nodeMap.getBalance() );

// eg: nodesArr[1] = net.addNode( "Label Node 1” , 0 );

// Fili list with arcs

fcr(NodeMap nodeMapSource : map.getMapNodeaO.values())(

for(Integer neighboursld : nodeMapSource.getNeighbours().keySetO){

IntVar arc = new IntVar(storę, nodeMapSource.getld{) + *>" + neighboursld, 0, SOD);

// eg.: new IntVar(storę, "1>2", arcLowerBound, arcOpperBound); < arc that connects nodes 1 and 2 arcList.add(arc);

int arcCost = map.getMapNodes().get(neighboursld).getCost(); // < "generał" cost, indicates obstacles etc.

Direction d ■ nodeMapSource.getNeighbours().get(neighboursld);

arcCost *= model.getDirectionCost().get(d); // cost multiplied by "wind cost"

net.addArcf nodesArray[ nodeMapSource.getldO ], nodesArray [neighboursld], arcCost,

// Variable that Stores total cost of a network solutionCost = new IntVar(storę, "cost”, 0, 9999); net.setCostVariable(solutionCost);

// Impose
