Q: I'm using a solver that supports warm-starts for integer problems. How do I communicate the initial solution to the solver?
A: You can use the setValue function on a variable to set its initial value, e.g.
@defVar(m, x[1:3], Int)
setValue(x[1], 10.0)
setValue(x[3], 2.0)If you don't set the value of a variable, the behavior is solver-dependent. Some solvers attempt to "complete" solutions that aren't completely specified.
