[gecode-users] use the print () method

[Christian Schulte]

This is basic C++ and not a Gecode question: you have to supply an object of
std::ostream (see the definition of the print function). Try std::cout to
print on the standard output.

Subject: [gecode-users] use the print () method

 

I had a problem with the print () method actually ENTERING AND MaximizeSpace
I want to maximize my profit in the hand when I wanted affichier the result
with the print method the compiler m 'displays the following error:

insufficient arguments in the apple function

I based my decision on this model already developed by you SendMoreMoney
model

 

below is an excerpt of my model

 

class manel : public MaximizeSpace {

protected:

          IntVarArray l;

  IntVar gain;

  static const int n=3;//nbre des testeurs 

  static const int m=3;//  nbre des noeuds

                      BoolVarArray a;

public:

          manel(void): a(*this,m*n,0,1),gain(*this,0,100000) {

                      

          Matrix <BoolVarArray> X (a,m,n);

 

          

                      vector<int> R;

 
R.push_back(20);R.push_back(30);R.push_back(40);

 

             vector<int> C;

                         C.push_back(50);C.push_back(60);C.push_back(70);

        vector<int> B;

                         B.push_back(80);B.push_back(90);B.push_back(70);

 

                      vector<int> Dr;

                         Dr.push_back(10);Dr.push_back(15);Dr.push_back(5);

                      vector<int> Dc;

                         Dc.push_back(7);Dc.push_back(5);Dc.push_back(2);

                      vector<int> Db;

                         Db.push_back(10);Db.push_back(7);Db.push_back(2);

                      vector<vector<int>> g;

                                  for(unsigned int i(0); i < n; ++i)

      g.emplace_back(std::vector<int>(m));

                      for(int i=0; i<n; i++)

                      {

                                  for (int j =0; j<m;j++)

                                              g[i][j]==50;

                      }

                                  //creation of constraints 

                                  // ... over rows

                      

                      for ( int j=0; j<n;j++)

                      {

 

                                              linear(*this ,

                      }

 

                      //... over columns

                                  

                              for (int i = 0; i < m; i++) {

 

                                                          linear(*this,

                                                }

                      {

                      linear(*this, g[i],X.row(i), IRT_EQ, gain);

 

                      }

 

 

                                              branch(*this, a,

           manel(bool share, manel& s)

i hope that you can help me with That
