This method has some advantages: first, it considers all the possible combinations of terms regardless of where/when they were proposed; second, the optimality criterion is the combination of terms that minimizes mismatches with the whole body of terms already proposed in the literature; third, the cost is calculated by comparison with all the available terms, one per reference, so no term has a larger a priori weight over others; and, fourth, the terms are not biased by authoritative considerations.
