Perhaps you should try some spelling variations:
"elements during algorithm" » "elements scheduling algorithm" (Expand Search), "elements cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"implement cc3d algorithm" » "implement rd algorithm" (Expand Search), "implemented cc3d algorithm" (Expand Search), "implementing cc3d 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: (((("implement cc3d algorithm") OR ("elements during algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement cc3d algorithm\") OR (\"elements during algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( implement cc3d algorithm ) OR ( elements during algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement cc3d algorithm") OR ("elements during algorithm"))) OR ("neural coding algorithm"))*.
