Here are some citaitons from Matlab Help and elsewhere. For arXiv publications, you cna search for publicaiotns in peer-revieweed journals also. Christodoulou (2019) generalizes the Soft Actor Critic algorithm to include discrete as well as continuous actions. Zhou (2022) is nother that you will probably find useful.
