Despite the difficulty of finding clear-cut distinctions since algorithms often share techniques common to more than one category, nevertheless we have found it useful to categorize them based on the type of information used and on the specific methodology [53, 54].
One such area of difficulty is the distinction between papillary and/or cribriform prostatic high-grade prostatic intraepithelial neoplasia (HG-PIN) and ductal adenocarcinoma.
Finally, as we have seen, the main issue that was encountered during the development of both the datasets and application was the difficulty of communicating to domain experts the distinction between human judgement and the mechanical application of modus ponens.
Only items 7 and 10 presented a minor problem of distinction between thresholds 1 and 2. In Table 3, the item difficulty was ranked according to their location parameters.
Nor is complexity theory incapable of making further distinctions about the difficulty of problems which lie inside \ \textbf{P}\) or between \ \textbf{P}\) and \ \textbf{NP}\) (presuming the latter class is non-empty).
