By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

F1(+2(x, y)) -> F1(y)
F1(+2(x, y)) -> F1(x)
F1(+2(x, s1(0))) -> F1(x)
Used argument filtering: F1(x1)  =  x1
+2(x1, x2)  =  +2(x1, x2)
s1(x1)  =  s
0  =  0
Used ordering: Quasi Precedence: trivial
