Initial complexity problem:

1:	T:

		(Comp: ?, Cost: 1)    f0(Ar_0, Ar_1) -> Com_1(f6(0, Fresh_0))

		(Comp: ?, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f6(Ar_0 + 1, Ar_1)) [ 49 >= Ar_0 ]

		(Comp: ?, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f14(Ar_0, Ar_1)) [ Ar_0 >= 50 ]

		(Comp: 1, Cost: 0)    koat_start(Ar_0, Ar_1) -> Com_1(f0(Ar_0, Ar_1)) [ 0 <= 0 ]

	start location:	koat_start

	leaf cost:	0



Repeatedly propagating knowledge in problem 1 produces the following problem:

2:	T:

		(Comp: 1, Cost: 1)    f0(Ar_0, Ar_1) -> Com_1(f6(0, Fresh_0))

		(Comp: ?, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f6(Ar_0 + 1, Ar_1)) [ 49 >= Ar_0 ]

		(Comp: ?, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f14(Ar_0, Ar_1)) [ Ar_0 >= 50 ]

		(Comp: 1, Cost: 0)    koat_start(Ar_0, Ar_1) -> Com_1(f0(Ar_0, Ar_1)) [ 0 <= 0 ]

	start location:	koat_start

	leaf cost:	0



A polynomial rank function with

	Pol(f0) = 1

	Pol(f6) = 1

	Pol(f14) = 0

	Pol(koat_start) = 1

orients all transitions weakly and the transition

	f6(Ar_0, Ar_1) -> Com_1(f14(Ar_0, Ar_1)) [ Ar_0 >= 50 ]

strictly and produces the following problem:

3:	T:

		(Comp: 1, Cost: 1)    f0(Ar_0, Ar_1) -> Com_1(f6(0, Fresh_0))

		(Comp: ?, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f6(Ar_0 + 1, Ar_1)) [ 49 >= Ar_0 ]

		(Comp: 1, Cost: 1)    f6(Ar_0, Ar_1) -> Com_1(f14(Ar_0, Ar_1)) [ Ar_0 >= 50 ]

A polynomial rank function with

	Pol(f0) = 50

	Pol(f6) = -V_1 + 50

	Pol(f14) = -V_1

	Pol(koat_start) = 50

orients all transitions weakly and the transition

	f6(Ar_0, Ar_1) -> Com_1(f6(Ar_0 + 1, Ar_1)) [ 49 >= Ar_0 ]

strictly and produces the following problem:
