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