void paramodulation_options(BOOL ordered_inference,
			    BOOL ordered_instance,
			    BOOL basic_paramodulation);

int basic_paramodulation_prunes(void);
How many paramodulants were killed because they failed the "basic" test.
void para_from_into(Clause from, Context cf,
		    Clause into, Context ci,
		    BOOL top_check,
		    void (*proc_proc) (Clause));
Paramodulate from one clause into another (non-backtrack unification version).

For oriented equality atoms, we go from left sides only and into both sides. For nonoriented equality atoms, we go from and into both sides.

"top_check" is used to prevent redundancy. If paramodulating C->D and then D->C, use top_check for the second call.


int para_instance_prunes();

Clause para_pos(Clause from, Ilist from_pos, Clause into, Ilist into_pos);
Construct a paramodulant from the given data. A fatal error occurs if it does not exist. In building the justification, the position vectors are copied.
