Arbital gives a distinction between “logical decision theory” and “functional decision theory” as:
Logical decision theories are a class of decision theories that have a logical counterfactual (vs. the causal counterfactual that CDT has and the evidential counterfactual EDT has).
Functional decision theory is the type of logical decision theory where the logical counterfactual is fully specified, and correctly gives the logical consequences of “decision function X outputs action A”.
Logical decision theory is the decision theory where the logical counterfactual is fully specified.
Functional decision theory is the incomplete variant of logical decision theory where the logical consequences of “decision function X outputs action A” have to be provided by the setup of the thought experiment.

More recently, I’ve seen in Decision theory does not imply that we get to have nice things:
Logical decision theory is the decision theory where the logical counterfactual is fully specified.
Functional decision theory is the incomplete variant of logical decision theory where the logical consequences of “decision function X outputs action A” have to be provided by the setup of the thought experiment.
