We are asked to determine termination of the following first-order TRS. 0 : [] --> o active : [o] --> o add : [o * o] --> o and : [o * o] --> o cons : [o * o] --> o false : [] --> o first : [o * o] --> o from : [o] --> o if : [o * o * o] --> o mark : [o] --> o nil : [] --> o ok : [o] --> o proper : [o] --> o s : [o] --> o top : [o] --> o true : [] --> o active(and(true, X)) => mark(X) active(and(false, X)) => mark(false) active(if(true, X, Y)) => mark(X) active(if(false, X, Y)) => mark(Y) active(add(0, X)) => mark(X) active(add(s(X), Y)) => mark(s(add(X, Y))) active(first(0, X)) => mark(nil) active(first(s(X), cons(Y, Z))) => mark(cons(Y, first(X, Z))) active(from(X)) => mark(cons(X, from(s(X)))) active(and(X, Y)) => and(active(X), Y) active(if(X, Y, Z)) => if(active(X), Y, Z) active(add(X, Y)) => add(active(X), Y) active(first(X, Y)) => first(active(X), Y) active(first(X, Y)) => first(X, active(Y)) and(mark(X), Y) => mark(and(X, Y)) if(mark(X), Y, Z) => mark(if(X, Y, Z)) add(mark(X), Y) => mark(add(X, Y)) first(mark(X), Y) => mark(first(X, Y)) first(X, mark(Y)) => mark(first(X, Y)) proper(and(X, Y)) => and(proper(X), proper(Y)) proper(true) => ok(true) proper(false) => ok(false) proper(if(X, Y, Z)) => if(proper(X), proper(Y), proper(Z)) proper(add(X, Y)) => add(proper(X), proper(Y)) proper(0) => ok(0) proper(s(X)) => s(proper(X)) proper(first(X, Y)) => first(proper(X), proper(Y)) proper(nil) => ok(nil) proper(cons(X, Y)) => cons(proper(X), proper(Y)) proper(from(X)) => from(proper(X)) and(ok(X), ok(Y)) => ok(and(X, Y)) if(ok(X), ok(Y), ok(Z)) => ok(if(X, Y, Z)) add(ok(X), ok(Y)) => ok(add(X, Y)) s(ok(X)) => ok(s(X)) first(ok(X), ok(Y)) => ok(first(X, Y)) cons(ok(X), ok(Y)) => ok(cons(X, Y)) from(ok(X)) => ok(from(X)) top(mark(X)) => top(proper(X)) top(ok(X)) => top(active(X)) We use the dependency pair framework as described in [Kop12, Ch. 6/7], with static dependency pairs (see [KusIsoSakBla09] and the adaptation for AFSMs in [Kop12, Ch. 7.8]). We thus obtain the following dependency pair problem (P_0, R_0, minimal, formative): Dependency Pairs P_0: 0] active#(add(s(X), Y)) =#> s#(add(X, Y)) 1] active#(add(s(X), Y)) =#> add#(X, Y) 2] active#(first(s(X), cons(Y, Z))) =#> cons#(Y, first(X, Z)) 3] active#(first(s(X), cons(Y, Z))) =#> first#(X, Z) 4] active#(from(X)) =#> cons#(X, from(s(X))) 5] active#(from(X)) =#> from#(s(X)) 6] active#(from(X)) =#> s#(X) 7] active#(and(X, Y)) =#> and#(active(X), Y) 8] active#(and(X, Y)) =#> active#(X) 9] active#(if(X, Y, Z)) =#> if#(active(X), Y, Z) 10] active#(if(X, Y, Z)) =#> active#(X) 11] active#(add(X, Y)) =#> add#(active(X), Y) 12] active#(add(X, Y)) =#> active#(X) 13] active#(first(X, Y)) =#> first#(active(X), Y) 14] active#(first(X, Y)) =#> active#(X) 15] active#(first(X, Y)) =#> first#(X, active(Y)) 16] active#(first(X, Y)) =#> active#(Y) 17] and#(mark(X), Y) =#> and#(X, Y) 18] if#(mark(X), Y, Z) =#> if#(X, Y, Z) 19] add#(mark(X), Y) =#> add#(X, Y) 20] first#(mark(X), Y) =#> first#(X, Y) 21] first#(X, mark(Y)) =#> first#(X, Y) 22] proper#(and(X, Y)) =#> and#(proper(X), proper(Y)) 23] proper#(and(X, Y)) =#> proper#(X) 24] proper#(and(X, Y)) =#> proper#(Y) 25] proper#(if(X, Y, Z)) =#> if#(proper(X), proper(Y), proper(Z))
