[Spot] Translations to DPA

Hi, I'm using / comparing Spot and other tools in the Rabin to Parity translation. I have two questions (to ensure my comparison is fair): 1) I want to minimize the input automata using Spot to remove the effects of preprocessing done by each tool as much as possible. However, I require that the acceptance condition remains a Rabin condition. Right now, I am using the call autfilt --remove-dead-states --cleanup-acceptance --remove-unused-ap --simplify-exclusive-ap --simplify-acc --partial-degeneralize --generalized-rabin --deterministic The last two are an effort to ensure that simplify-acc doesn't change the acceptance condition. 2) What are the ways to tell spot to translate DRA to DPA? Right now, I am using autfilt --hoa --deterministic --parity. This seems to be a sort of black box (which is fine with me). Just to make sure: Are there other DRA-to-DPA translations included in Spot which are worthwhile to be investigated? Cheers, Tobias
