The following dependency pair can be strictly oriented:

REV1(x, ++(y,z)) -> REV1(y,z)

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:

REV1(x,_{1}x) ->_{2}x_{2}

++(x,_{1}x) -> ++(_{2}x,_{1}x)_{2}
