Optimal control of opinion dynamics.

Depending on which numerical tolerances are used, different optimal solution values are reported for this instance.
The best solution passing the solution checker has value -6.6556387297. However, fixing all integer variables
to exact integer values, the resulting LP was shown to be infeasible by QSopt_ex, an exact LP solver.
The best solution that corresponds to an exact solution known so far has solution value -6.652756.
