Yes for some definitions of maximizers. The article Stuart_Armstrong wrote seems have to differing definitions: maximizers are agents that seek to get as much X as possible, and his satisficers want to get as much E(X) as possible. Then, trivially, those reduce to agents that want to get as much X as possible.

I don't see that as novel or relevant since what I would call satisficers are those that try to set marginal gain equal to marginal cost. Those generally do not reduce to agents that seek to get as much X as possible.
