10 Some modification of this scheme is necessary when the input stream is not deterministic . For the A * algorithm ( Hart et al. 1968 ) as applied to speech recognition , the actual path score is typically augmented with an estimated score for the unseen portion . Unless some kind of normalization is done , the short theories have an unfair advantage , simply because fewer probability scores have been multiplied .
