Perhaps you should try some spelling variations:
"elements present algorithm" » "elements presented algorithm" (Expand Search), "elements treatment algorithm" (Expand Search), "elements forest algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data 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: (("elements present algorithm") OR ((("element data algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements present algorithm\") OR (((\"element data algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements present algorithm ) OR ((( element data algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements present algorithm") OR ((("element data algorithms") OR ("neural coding algorithm"))))*.
