Left Termination proof of /tmp/tmp7SfJeO/pl7.6.2b.pl

Left Termination of the query pattern reach_in_4(g, g, g, g) w.r.t. the given Prolog program could not be shown:

↳ Prolog

  ↳ PrologToPiTRSProof

  ↳ PrologToPiTRSProof

Clauses:

reach(X, Y, Edges, Visited) :- member(.(X, .(Y, [])), Edges).
reach(X, Z, Edges, Visited) :- ','(member1(.(X, .(Y, [])), Edges), ','(member(Y, Visited), reach(Y, Z, Edges, .(Y, Visited)))).
member(H, .(H, L)).
member(X, .(H, L)) :- member(X, L).
member1(H, .(H, L)).
member1(X, .(H, L)) :- member1(X, L).

Queries:

reach(g,g,g,g).

We use the technique of [30]. With regard to the inferred argument filtering the predicates were used in the following modes:
reach_in: (b,b,b,b)
member_in: (b,b)
member1_in: (f,b)

The TRS R consists of the following rules:

member_in_gg(H, .(H, L)) → member_out_gg
member_in_gg(X, .(H, L)) → U5_gg(member_in_gg(X, L))
member1_in_ag(.(H, L)) → member1_out_ag(H)
member1_in_ag(.(H, L)) → U6_ag(member1_in_ag(L))
U5_gg(member_out_gg) → member_out_gg
U6_ag(member1_out_ag(X)) → member1_out_ag(X)

s = U3_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, z5), z2, member_out_gg) evaluates to t =U3_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5)), z2, member_out_gg)

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

Matcher: [z5 / .(z2, z5)]
Semiunifier: [ ]

Rewriting sequence

U3_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, z5), z2, member_out_gg) → REACH_IN_GGGG(z2, z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5)))

REACH_IN_GGGG(z2, z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5))) → U2_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5)), member1_out_ag(.(z1, .(z2, []))))
with rule REACH_IN_GGGG(x0, x1, .(.(y_6, .(y_7, [])), x3), .(x0, .(x4, x5'))) → U2_GGGG(x1, .(.(y_6, .(y_7, [])), x3), .(x0, .(x4, x5')), member1_out_ag(.(y_6, .(y_7, [])))) at position [] and matcher [x1 / z0, x4 / z2, y_6 / z1, x3 / z3, x0 / z2, x5' / z5, y_7 / z2]

U2_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5)), member1_out_ag(.(z1, .(z2, [])))) → U3_GGGG(z0, .(.(z1, .(z2, [])), z3), .(z2, .(z2, z5)), z2, member_out_gg)

Now applying the matcher to the start term leads to a term which is equal to the last term in the rewriting sequence

All these steps are and every following step will be a correct step w.r.t to Q.

We use the technique of [30]. With regard to the inferred argument filtering the predicates were used in the following modes:
reach_in: (b,b,b,b)
member_in: (b,b)
member1_in: (f,b)

We have to consider all (P,Q,R)-chains.
