(ignored inputs)COMMENT full experiments for [35] submitted by: Takahito Aoto and Yoshihito Toyama
Input:
   [ or(?x,T) -> T,
     or(?x,F) -> ?x,
     or(?x,?y) -> or(?y,?x) ]

Make it flat:
   [ or(?x,T) -> T,
     or(?x,F) -> ?x,
     or(?x,?y) -> or(?y,?x) ]
Time: 0.000 [s]

Make it Complete (R^):
   [ or(?x,T) = or(T,F),
     or(?x,T) = or(F,T),
     or(?x,T) = or(?x_1,T),
     or(T,?x) = or(T,F),
     or(T,?x) = or(F,T),
     or(T,?x) = or(?x_1,T),
     or(T,?x) = or(T,?x_1),
     T = or(T,?x),
     or(T,F) = or(F,T),
     T = or(F,T),
     T = or(T,F),
     or(?x,T) = T,
     or(F,F) = F,
     or(?x,F) = or(F,?x),
     ?x = or(F,?x),
     or(?x,F) = ?x,
     or(?x,?y) = or(?y,?x) ]
