In the loop for (ittération) I would to make the sum between each countPV cell of the last ittération   and the newest .

In main script, i can't mak the sum etween two arrays cell per cell.

 

My model:

 

{int} contPM;

int VMmin=1;
int VMmax=4;
int VM[i in V]=VMmin+rand(VMmax-VMmin+1);
string S[VMmin..VMmax]=["s","m","l","xl"];
string vms[i in V]=S[VM[i]];
{string} VMTypes={S[v] | v in VMmin..VMmax};

 

//PreProcess
 ....

//the model/problem definition

dvar boolean lumda[V][P];
dexpr int O = sum( i in V, j in P) lumda[i][j];
dexpr int OPPMVMS[vmtype in VMTypes][ptype in P]=sum( j in P, i in V:j==ptype&&vms[i]==vmtype) lumda[i][j];
maximize O;

//constraints

....

tuple PM
{
  int npm;
  string nvm;
  }
{PM} indexes={<i,j> | i in P,j in VMTypes};
int countPV[ <i,j> in indexes]=OPPMVMS[j][i]; 
 
{int} countPM={j | i in V,j in P:lumda[i][j]==1 };
int pm= card(countPM);

main

 

{var res = new Array();

var min=10;
var max=30;
var mix=max-min+1;

for(var j=1;j<120;j=j+(min+(Opl.rand(mix))))
{

for (var i=1; i<=NbI;i++)
{
  writeln("######Ittération number ", i,"#######");

   var masterDef = thisOplModel.modelDefinition;
   var masterCplex = cplex;
   var masterData = thisOplModel.dataElements;   
   // Creating the master-model
   var masterOpl = new IloOplModel(masterDef, masterCplex);
   masterData.v=j;
   masterOpl.addDataSource(masterData);
   writeln("solving with ",j,"  vms");
   masterOpl.generate();

    if ( masterCplex.solve() )
       {

I want to store in an array of same size that countVP the sum of each cell of countPV  for  the n ittérations:

res[i]=res[i]+masteOpl.countPV[i]
      }

 

else

{}

 

}end n ittérations

for(var i in res)

//the average

res[i]=res[i]/Number of ittérations

}end second loop for

      }

}

Thanks

Hi,

let me give you a small example:

You have sub.mod

float maxOfx = ...;
dvar float x[1..10];

maximize sum(i in 1..10)x[i];
subject to {
  forall(i in 1..10) x[i]<=maxOfx;
}

and sub.dat

 

maxOfx=10;

then

 range r=1..10;
 int sumofresults[i in 1..10]=0;
 
 main {
  var source = new IloOplModelSource("sub.mod");
  var cplex = new IloCplex();
  var def = new IloOplModelDefinition(source);
 
  var maxOfx=0;
 
  for(var k=1;k<=10;k++)
  {
  maxOfx=k;  
 
 
  var opl = new IloOplModel(def,cplex);
  var data= new IloOplDataElements();
 
  writeln(maxOfx);
  data.maxOfx=maxOfx;
  opl.addDataSource(data);
  opl.generate();

  if (cplex.solve()) {
  opl.postProcess();  
 
     for(var i in thisOplModel.r) thisOplModel.sumofresults[i]+=opl.x[i]*1.0;
  } else {
     writeln("No solution");
  }

 
 
}  

writeln("sumofresults=",thisOplModel.sumofresults)
 
}

 

will put results into an array

Why do I get the following runtime error with the example you provided?

    Element "maxOfx" not defined.

 

Thanks.

Hi,

let us call main.mod the third code I wrote.

You should do

oplrun main.mod

or in the IDE launch a run configuration with only main.mod

Is that what you did ?

Hi,

is it working now ?
