Save the number of variables #3

Closed riccardodebenedictis closed 5 years ago

Check the execution of the expression statements. Asserting facts could be refactored, exploiting the ν variable and the controllable operators introduced in commit 14f7fdb13c15bc6e8280e7eaf9ab7913294135b8, so as to save the number of propositional variables.

this number of variable saving, probably, cannot be done

consider the following example: we want to introduce the constraint x∨y this should result in the introduction of the constraint ν⇒x∨y which is different from ν=x∨y as it would result from using the controllable operators introduced in commit 14f7fdb13c15bc6e8280e7eaf9ab7913294135b8

in other words, the implied term should be free to become true without affecting the implying term.
