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)
"element abs algorithm" » "element anbs algorithm" (Expand Search), "element pass algorithm" (Expand Search), "element b algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (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: (("element abs algorithm") OR ((("element mapping algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element abs algorithm\") OR (((\"element mapping algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element abs algorithm ) OR ((( element mapping algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element abs algorithm") OR ((("element mapping algorithm") OR ("neural coding algorithm"))))*.
