Re: [tlaplus] Defining State_I as the state at energy level \epsilon(I)

[Stephan Merz <stephan.merz@xxxxxxxxx>]

TLA+ has bounded set comprehension:

{ x \in S : P(x) }

Unbounded comprehension is disallowed: this helps making the definition of Russell’s “set” illegal.

State_I \in {energy_level : energy_level = \epsilon(I)}
