Termination w.r.t. Q of the following Term Rewriting System could be proven:
Q restricted rewrite system:
The TRS R consists of the following rules:
sqr(0) → 0
sqr(s(x)) → +(sqr(x), s(double(x)))
double(0) → 0
double(s(x)) → s(s(double(x)))
+(x, 0) → x
+(x, s(y)) → s(+(x, y))
sqr(s(x)) → s(+(sqr(x), double(x)))
Q is empty.

Q is empty.
We use [23] with the following order to prove termination.
Lexicographic path order with status [19].
Precedence:
sqr1 > +2 > s1
sqr1 > double1 > s1
Status:
trivial
