Reference manual / Z-related commands / Decision procedure commands / linear solution


The linear solution command reveals the solutions found by the linear decision command. It effectively uses a quantification tac command to reveal the solutions. The linear solution command is applicable to universal and existential quantification predicates to which the linear decision command is also applicable. For an existential quantification that is true, linear solution reveals a solution. For a universal quantification that is false, linear solution reveals a counter-example. It effectively uses a quantification tac command to reveal the solutions.

In the cases where there is no solution or counter-example, linear solution reports ``Nothing changed''.

Tactic example

"linear solution" p1 p2

This example applies the linear solution command to predicates p1 and p2.
