Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"cell models algorithm" » "cell modeling algorithm" (Expand Search), "cell novel algorithm" (Expand Search), "cell modbo algorithm" (Expand Search), "cell model algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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: (((("elements method algorithm") OR ("cell models algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"cell models algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( cell models algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("cell models algorithm"))) OR ("neural coding algorithm"))*.
