Termination proof

1: switching to dependency pairs

The following set of initial dependency pairs has been identified.

a__tail#( cons( X , XS ) ) mark#( XS )
mark#( zeros ) a__zeros#
mark#( tail( X ) ) a__tail#( mark( X ) )
mark#( tail( X ) ) mark#( X )
mark#( cons( X1 , X2 ) ) mark#( X1 )

1.1: dependency graph processor

The dependency pairs are split into 1 component(s).
