**ACKIN(s( X), s(Y)) -> ACKIN(s(X), Y)**

ackin(s(X), s(Y)) -> u21(ackin(s(X),Y),X)

u21(ackout(X),Y) -> u22(ackin(Y,X))

The following dependency pair can be strictly oriented:

ACKIN(s(X), s(Y)) -> U21(ackin(s(X),Y),X)

There are no usable rules w.r.t. to the AFS that need to be oriented.

Used ordering: Homeomorphic Embedding Order with EMB

resulting in one new DP problem.

Used Argument Filtering System:

ACKIN(x,_{1}x) ->_{2}x_{1}

s(x) -> s(_{1}x)_{1}

U21(x,_{1}x) ->_{2}x_{2}

ackin(s(X), s(Y)) -> u21(ackin(s(X),Y),X)

u21(ackout(X),Y) -> u22(ackin(Y,X))

Using the Dependency Graph the DP problem was split into 1 DP problems.
