% 2.33/1.58 %------ If we have equality in the problem then it is also defined as a predicate above,
% 2.33/1.58 %------ with "=" on the right-hand-side of the definition interpreted over the term algebra term_algebra_type
% 2.33/1.58 %------ See help for --sat_out_model for different model outputs.
% 2.33/1.58 %------ equality_sorted(X0,X1,X2) can be used in the place of usual "="
