Hi;

Would you please let me know when we are using "ilo" in modeling for instance iloconstraint,... ! Why some of them are written as "constraint"?

Thanks

Dear FIFIla,

Ilo prefixed object types are modeling ones. Thus you will use IloIntVar when you want to create an integer variable in your model. For instance, the following snippets

create an "all different" constraint on an array of variables "x". It uses "Ilo" data types "IloIntVarArray" and "IloAllDiff" to create variables and constraints respectively.

#include <ilcp/cp.h>

int main() {
  IloEnv                env;
  IloIntVarArray        x(env, 10, 0, 9);
  IloModel              m(env);
  m.add(IloAllDiff(env, x));
  IloCP                 cp(m);
  
  cp.solve();
  for(IloInt i = 0; i < 10; ++i)
    std::cout << "x[" << i << "] = " << cp.getValue(x[i]) << std::endl;
  cp.end();
  env.end();
  return 0;
}

I hope this helps.

Cheers,
