Perhaps you should try some spelling variations:
"complement lectin algorithm" » "complement selection algorithm" (Expand Search), "complement location algorithm" (Expand Search), "complement leiden algorithm" (Expand Search), "implement lectin algorithm" (Expand Search), "complementary lectin algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element group algorithm" » "element growth algorithm" (Expand Search), "recent group algorithm" (Expand Search), "supplement group 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: (("complement lectin algorithm") OR ((("element group algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"complement lectin algorithm\") OR (((\"element group algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( complement lectin algorithm ) OR ((( element group algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("complement lectin algorithm") OR ((("element group algorithm") OR ("neural coding algorithm"))))*.
