We also do not check for periodicity when check ahead periods have been increased endogenously, again to avoid mis-identified periodicity.
Any other type of periodicity, is flagged as non-convergence with error code 313 (infinite loop of solutions).
when performing stochastic simulations, check ahead periods may increase endogenously at some point for regimes very long in expectation. such longer check ahead periods may considerably slow down convergence in subsequent periods, so users may want to avoid this.
1) algo_truncation: sets the number of iterations for a truncated guess-verify algorithm (i.e. if max_iter<=algo_truncation, no error is triggered on output, but the user is happy with the last regime in the algorithm)
2) reset_regime_in_new_period: is set to true, it resets the guess regimes to unconstrained when a new shock arrives, instead of starting with a guess regime consistent with the one identified in previous time periods. this sometimes allows more robust convergence/identification of the regimes
