The system is accessible function passing by a sort ordering that equates all sorts. We start by computing the following initial DP problem: P1. (1) minus#(U, s(V)) => minus#(U, V) (2) minus#(U, s(V)) => pred#(minus(U, V)) (3) quot#(s(P), s(X1)) => minus#(P, X1) (4) quot#(s(P), s(X1)) => quot#(minus(P, X1), s(X1)) (5) map#(G1, cons(V1, W1)) => map#(G1, W1) (6) filter#(F2, cons(Y2, U2)) => filter2#(F2(Y2), F2, Y2, U2) (7) filter2#(true, H2, W2, P2) => filter#(H2, P2) (8) filter2#(false, F3, Y3, U3) => filter#(F3, U3) ***** We apply the Graph Processor on P1. Considering the 4 SCCs, this DP problem is split into the following new problems. P2. (1) minus#(U, s(V)) => minus#(U, V) P3. (1) quot#(s(P), s(X1)) => quot#(minus(P, X1), s(X1)) P4. (1) map#(G1, cons(V1, W1)) => map#(G1, W1) P5. (1) filter#(F2, cons(Y2, U2)) => filter2#(F2(Y2), F2, Y2, U2) (2) filter2#(true, H2, W2, P2) => filter#(H2, P2) (3) filter2#(false, F3, Y3, U3) => filter#(F3, U3) ***** We apply the Subterm Criterion Processor on P2. We use the following projection function: nu(minus#) = 2 We thus have: (1) s(V) |>| V All DPs are strictly oriented, and may be removed. Hence, this DP problem is finite. ***** No progress could be made on DP problem P3.
