P = sif#(true, I0, I1) -> sum#(I0, I1 + 1) sum#(I2, I3) -> sif#(I2 >= I3, I2, I3) R = sif(false, x, y) -> 0 sif(true, I0, I1) -> I1 + sum(I0, I1 + 1) sum(I2, I3) -> sif(I2 >= I3, I2, I3) This problem is converted using chaining, where edges between chained DPs are removed. DP problem for innermost termination. P = sif#(true, I0, I1) -> sum#(I0, I1 + 1) sum#(I2, I3) -> sif#(I2 >= I3, I2, I3) sum#(I2, I3) -> sum#(I2, I3 + 1) [I2 >= I3] R = sif(false, x, y) -> 0 sif(true, I0, I1) -> I1 + sum(I0, I1 + 1) sum(I2, I3) -> sif(I2 >= I3, I2, I3) The dependency graph for this problem is: 0 -> 2, 1 1 -> 2 -> 2, 1 Where: 0) sif#(true, I0, I1) -> sum#(I0, I1 + 1) 1) sum#(I2, I3) -> sif#(I2 >= I3, I2, I3) 2) sum#(I2, I3) -> sum#(I2, I3 + 1) [I2 >= I3] We have the following SCCs. { 2 } DP problem for innermost termination. P = sum#(I2, I3) -> sum#(I2, I3 + 1) [I2 >= I3] R = sif(false, x, y) -> 0 sif(true, I0, I1) -> I1 + sum(I0, I1 + 1) sum(I2, I3) -> sif(I2 >= I3, I2, I3) We use the reverse value criterion with the projection function NU: NU[sum#(z1,z2)] = z1 + -1 * z2 This gives the following inequalities: I2 >= I3 ==> I2 + -1 * I3 > I2 + -1 * (I3 + 1) with I2 + -1 * I3 >= 0 All dependency pairs are strictly oriented, so the entire dependency pair problem may be removed. popout
