Q is empty.
The following rules can be removed by the rule removal processor [15] because they are oriented strictly by a polynomial ordering:
and(x, y) → if(x, y, false)
or(x, y) → if(x, true, y)
implies(x, y) → if(x, y, true)
if(true, x, y) → x
Used ordering:
Polynomial interpretation [25]:
POL(=(x1, x2)) = 1 + 2·x1 + 2·x2
POL(and(x1, x2)) = 1 + 2·x1 + 2·x2
POL(false) = 0
POL(if(x1, x2, x3)) = x1 + x2 + x3
POL(implies(x1, x2)) = 2 + 2·x1 + x2
POL(not(x1)) = 1 + x1
POL(or(x1, x2)) = 2 + x1 + 2·x2
POL(true) = 1
