Initial complexity problem:
1:	T:
		(?, 1)    eval(a, b, c) -> eval(a + b, b - 2, c + 1) [ a >= 0 ]
		(?, 1)    eval(a, b, c) -> eval(a + c, b, c - 2) [ a >= 0 ]
		(1, 1)    start(a, b, c) -> eval(a, b, c)
	start location:	start
	leaf cost:	0

By chaining the transition start(a, b, c) -> eval(a, b, c) with all transitions in problem 1, the following new transitions are obtained:
	start(a, b, c) -> eval(a + c, b, c - 2) [ a >= 0 ]
	start(a, b, c) -> eval(a + b, b - 2, c + 1) [ a >= 0 ]
We thus obtain the following problem:
2:	T:
		(1, 2)    start(a, b, c) -> eval(a + c, b, c - 2) [ a >= 0 ]
		(1, 2)    start(a, b, c) -> eval(a + b, b - 2, c + 1) [ a >= 0 ]

		(?, 1)    eval(a, b, c) -> eval(a + c, b, c - 2) [ a >= 0 ]
	start location:	start
	leaf cost:	0

By chaining the transition start(a, b, c) -> eval(a + c, b, c - 2) [ a >= 0 ] with all transitions in problem 2, the following new transitions are obtained:
	start(a, b, c) -> eval(a + 2*c - 2, b, c - 4) [ a >= 0 /\ a + c >= 0 ]
	start(a, b, c) -> eval(a + c + b, b - 2, c - 1) [ a >= 0 /\ a + c >= 0 ]
We thus obtain the following problem:
3:	T:

By chaining the transition start(a, b, c) -> eval(a + 2*c - 2, b, c - 4) [ a >= 0 /\ a + c >= 0 ] with all transitions in problem 3, the following new transitions are obtained:
	start(a, b, c) -> eval(a + 3*c - 6, b, c - 6) [ a >= 0 /\ a + c >= 0 /\ a + 2*c - 2 >= 0 ]
	start(a, b, c) -> eval(a + 2*c + b - 2, b - 2, c - 3) [ a >= 0 /\ a + c >= 0 /\ a + 2*c - 2 >= 0 ]
We thus obtain the following problem:

We thus obtain the following problem:
