I don't understand what the notation means.
For example when the author says:
P(Q ⊆ X | ∀ x ∈ Q (x = 1))
This is equivalent to P(Q ⊆ X | Q = {1}), which further simplifies to P(1∈X).
This seems to be a type error (isn't X supposed to be a set of binary variables?), and also an awfully cumbersome way to write P(1∈X).
Anyone have some idea what the article is trying to say?
- usgroup 11mo agoIt's a typo. Its supposed to be a comma not a pipe, and read P(Q ⊆ X , ∀ x ∈ Q (x = 1)). I.e. Q is some subset of X and for all x in Q, x=1.
