Quick stupid question: what does "A[]->O" stand for? specifically "[]->"? Is that a material implication? Should I read it as "P(O|A is the output of this computation and rest of universe)"?

(edit): could someone please help with this?

It means "If A were true, then O would be true." Note that this is a counterfactual statement.
