Perhaps you should try some spelling variations:
"elements finding algorithm" » "element bonding algorithm" (Expand Search), "elements including algorithm" (Expand Search), "elements within algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural routing algorithm" (Expand Search)
"element forest algorithm" » "element ore 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 forest algorithm") OR ("elements finding algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"elements finding algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( elements finding algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("elements finding algorithm"))) OR ("neural coding algorithm"))*.
