IBM ILOG OPL JavaScript Reference: Class IloNumVar

Class IloNumVar

IloNumExpr
   |
   +--IloNumVar

Description:

Using an IloNumVar object implicitly provides access to its solutionValue property. The postprocessing expression

  x*100

is equivalent to

  x.solutionValue * 100

where x has been declared as

  dvar float x;

in the modeling part.

Example:

dvar float x in 0..20;

maximize x;

subject to {
}

execute {
  writeln(x.name);
  writeln(x.LB," ",x.UB," ",x.solutionValue);
  writeln(x.reducedCost);
}

After execution, the Scripting log shows:

x
0 20 20
1
