P = ft#(true, x, y) -> ft#(y >= x, x + 1, y) f#(true, I0) -> ft#(true, I0, I1) R = ft(true, x, y) -> ft(y >= x, x + 1, y) f(true, I0) -> ft(true, I0, I1) This problem is converted using chaining, where edges between chained DPs are removed. DP problem for innermost termination. P = ft#(true, x, y) -> ft_1#(x, y) f#(true, I0) -> ft#(true, I0, I1) ft_1#(x, y) -> ft#(y >= x, x + 1, y) ft_1#(x, y) -> ft_1#(x + 1, y) [y >= x] f#(true, I0) -> ft_1#(I0, I1) [true] R = ft(true, x, y) -> ft(y >= x, x + 1, y) f(true, I0) -> ft(true, I0, I1) The dependency graph for this problem is: 0 -> 3, 2 1 -> 2 -> 3 -> 3, 2 4 -> 2, 3 Where: 0) ft#(true, x, y) -> ft_1#(x, y) 1) f#(true, I0) -> ft#(true, I0, I1) 2) ft_1#(x, y) -> ft#(y >= x, x + 1, y) 3) ft_1#(x, y) -> ft_1#(x + 1, y) [y >= x] 4) f#(true, I0) -> ft_1#(I0, I1) [true] We have the following SCCs. { 3 } DP problem for innermost termination. P = ft_1#(x, y) -> ft_1#(x + 1, y) [y >= x] R = ft(true, x, y) -> ft(y >= x, x + 1, y) f(true, I0) -> ft(true, I0, I1) We use the reverse value criterion with the projection function NU: NU[ft_1#(z1,z2)] = z2 + -1 * z1 This gives the following inequalities: y >= x ==> y + -1 * x > y + -1 * (x + 1) with y + -1 * x >= 0 All dependency pairs are strictly oriented, so the entire dependency pair problem may be removed. popout
