Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


REN3(X, Y, apply2(T, S)) -> REN3(X, Y, T)
REN3(X, Y, apply2(T, S)) -> REN3(X, Y, S)
The remaining pairs can at least be oriented weakly.

REN3(X, Y, lambda2(Z, T)) -> REN3(X, Y, ren3(Z, var1(cons2(X, cons2(Y, cons2(lambda2(Z, T), nil)))), T))
REN3(X, Y, lambda2(Z, T)) -> REN3(Z, var1(cons2(X, cons2(Y, cons2(lambda2(Z, T), nil)))), T)
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( REN3(x1, ..., x3) ) = max{0, x3 - 2}


POL( apply2(x1, x2) ) = x1 + x2 + 3


POL( lambda2(x1, x2) ) = x2


POL( ren3(x1, ..., x3) ) = x3


POL( var1(x1) ) = 0


POL( if3(x1, ..., x3) ) = 0



The following usable rules [14] were oriented:

if3(true, var1(K), var1(L)) -> var1(K)
ren3(X, Y, lambda2(Z, T)) -> lambda2(var1(cons2(X, cons2(Y, cons2(lambda2(Z, T), nil)))), ren3(X, Y, ren3(Z, var1(cons2(X, cons2(Y, cons2(lambda2(Z, T), nil)))), T)))
if3(false, var1(K), var1(L)) -> var1(L)
ren3(var1(L), var1(K), var1(Lp)) -> if3(eq2(L, Lp), var1(K), var1(Lp))
ren3(X, Y, apply2(T, S)) -> apply2(ren3(X, Y, T), ren3(X, Y, S))
