Hello,

In OPL, I initialize MIP starts as follows: 

var vectors = new IloOplCplexVectors();
vectors.attach(model.decsionvariable, data.valuestobeattached);

vectors.setVectors( cplex )

I would like to initialize multiple MIP starts. To accomplish that, I use the procedure above, but each time I declare different vectors1, vectors2 and so on. Somehow, CPLEX still recognizes one MIP start. I was wondering why this happens.

Thank you!

Hi,

have you tried addMIPStart ?

Hi,

let me give you an example:

in the warmstart example,

replace

vectors.attach(opl2.x,opl2.values);
  vectors.setVectors(cplex2);   
 
 by

  cplex2.addMIPStart(opl2.x,opl2.values,1);

regards
