*maxit* is maximum number of iterations (default 20). If the calculation does not
converge in the default number of iterations, you should first think about the reason
before increasing the limit. In most cases the choice of active orbitals or of the
optimized states is not appropriate (see introduction of MULTI). The maximum allowed value
of *maxit* is 40. If the calculation has not converged in this number of iterations,
it is likely that the active space is not reasonable. Note: slow convergence can occur
in RASSCF calculations if single excitations into weakly occupied orbitals are present.
These should be eliminated using

`RESTRICT,-1,-1`,*orbital list*
