Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"tests learning algorithms" » "meta learning algorithms" (Expand Search), "students learning algorithms" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("tests learning algorithms") OR ((("element mapping algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tests learning algorithms\") OR (((\"element mapping algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( tests learning algorithms ) OR ((( element mapping algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("tests learning algorithms") OR ((("element mapping algorithm") OR ("neural coding algorithm"))))*.
