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