Perhaps you should try some spelling variations:
"patients presented algorithm" » "patients presenting algorithm" (Expand Search), "patients treated algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements cnn algorithm" » "elements mean algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements upon 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: (((("patients presented algorithm") OR ("elements cnn algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"patients presented algorithm\") OR (\"elements cnn algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( patients presented algorithm ) OR ( elements cnn algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("patients presented algorithm") OR ("elements cnn algorithm"))) OR ("neural coding algorithm"))*.
