Initial complexity problem:

		(Comp: ?, Cost: 1)    f0(Ar_0, Ar_1) -> Com_1(f3(1, Ar_1))

		(Comp: ?, Cost: 1)    f3(Ar_0, Ar_1) -> Com_1(f3(Ar_0 + 1, -Ar_0 + 10)) [ 10 >= Ar_0 ]

		(Comp: ?, Cost: 1)    f3(Ar_0, Ar_1) -> Com_1(f10(Ar_0, Ar_1)) [ Ar_0 >= 11 ]

A polynomial rank function with

	Pol(f0) = 1

	Pol(f3) = 1

	Pol(f10) = 0

	Pol(koat_start) = 1

orients all transitions weakly and the transition

	f3(Ar_0, Ar_1) -> Com_1(f10(Ar_0, Ar_1)) [ Ar_0 >= 11 ]

strictly and produces the following problem:
