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