Args:
operator: The Ising Hamiltonian as an Operator
timelimit: A time limit in seconds for the execution
thread: The number of threads that CPLEX uses. Setting this 0 lets CPLEX decide the
number of threads to allocate, but this may not be ideal for small problems for
which the default of 1 is more suitable.
display: Decides what CPLEX reports to the screen and records in a log during
mixed integer optimization. This value must be between 0 and 5 where the
amount of information displayed increases with increasing values of this parameter.
