To avoid non-valid extrapolation, the validity domain of PTFs should be investigated.
But the non-valid first-order sentences are not recursively enumerable, hence neither are the validities for the modal system MFC.
A is then also a non-valid sentence of MFC.
Non-valid responses were: duplication; core questions being incomplete.
Additionally to their robustness, GAs can handle non-valid data which may appear during the optimization.
Otherwise, all the permutations represented by the resulting tree are non-valid, because conflicting restrictions cannot be fulfilled.
The total person-year observations are 180,543, after excluding for non-response and non-valid values of the variables.
And nearly ten-fold reduction in administration of medicines against non-valid prescriptions from 0.38 % to 0.4%% (p < 0.001).
What was missing was a procedure to list out all the non-valid formulas, or equivalently to list out all satisfiable formulas.
Thus, a cell will be considered 'valid' when its ratio of non-valid points, r nv, is less than a prefixed threshold τ nv.
Note that the points whose CIRCON images obtain a low similarity value are stored in a list of non-valid indexes, ind nv.
