@metesynnada and @berkaysynnada -- I would appreciate it if you could double check this example. I think this is the kind of thing propagate_constraints can do, but I am not 100% sure I got the example correct

The example you gave is clear and correct, thank you ☺️
For more detail:

  • For plus operation, specifically, we would first do
  • [a_lower, a_upper] <- ([expression_lower, expression_upper] - [b_lower, b_upper]) ∩ [a_lower, a_upper], and then
  • [b_lower, b_upper] <- ([expression_lower, expression_upper] - [a_lower, a_upper]) ∩ [b_lower, b_upper].
