output

YES DP problem for innermost termination. P = init#(x1, x2) -> f1#(rnd1, rnd2) f2#(I0, I1) -> f2#(I0 - 1, I1 - 1) [0 <= I0 - 1 /\ 0 <= I1 - 1] f1#(I2, I3) -> f2#(I4, I5) [0 <= I2 - 1 /\ -1 <= I5 - 1 /\ -1 <= I3 - 1 /\ -1 <= I4 - 1] R = init(x1, x2) -> f1(rnd1, rnd2) f2(I0, I1) -> f2(I0 - 1, I1 - 1) [0 <= I0 - 1 /\ 0 <= I1 - 1] f1(I2, I3) -> f2(I4, I5) [0 <= I2 - 1 /\ -1 <= I5 - 1 /\ -1 <= I3 - 1 /\ -1 <= I4 - 1] The dependency graph for this problem is: 0 -> 2 1 -> 1 2 -> 1 Where: 0) init#(x1, x2) -> f1#(rnd1, rnd2) 1) f2#(I0, I1) -> f2#(I0 - 1, I1 - 1) [0 <= I0 - 1 /\ 0 <= I1 - 1] 2) f1#(I2, I3) -> f2#(I4, I5) [0 <= I2 - 1 /\ -1 <= I5 - 1 /\ -1 <= I3 - 1 /\ -1 <= I4 - 1] We have the following SCCs. { 1 } DP problem for innermost termination. P = f2#(I0, I1) -> f2#(I0 - 1, I1 - 1) [0 <= I0 - 1 /\ 0 <= I1 - 1] R = init(x1, x2) -> f1(rnd1, rnd2) f2(I0, I1) -> f2(I0 - 1, I1 - 1) [0 <= I0 - 1 /\ 0 <= I1 - 1] f1(I2, I3) -> f2(I4, I5) [0 <= I2 - 1 /\ -1 <= I5 - 1 /\ -1 <= I3 - 1 /\ -1 <= I4 - 1] We use the basic value criterion with the projection function NU: NU[f2#(z1,z2)] = z2 This gives the following inequalities: 0 <= I0 - 1 /\ 0 <= I1 - 1 ==> I1 >! I1 - 1 All dependency pairs are strictly oriented, so the entire dependency pair problem may be removed. popout
