brandNewClause

public static OriginalHTClausePB brandNewClause(UnitPropagationListener s,
                                                ILits voc,
                                                IVecInt literals)

Creates a brand new clause, presumably from external data. Performs all sanity checks.

Parameters:

s - the object responsible for unit propagation

voc - the vocabulary

literals - the literals to store in the clause

Returns:

the created clause or null if the clause should be ignored (tautology for example)
