Perhaps you should try some spelling variations:
"develop cosine algorithm" » "develop colony algorithm" (Expand Search), "developed cosine algorithm" (Expand Search)
"elements data algorithm" » "elements jaya algorithm" (Expand Search), "elements deer algorithm" (Expand Search)
"data backing algorithm" » "data banking algorithm" (Expand Search), "data lacking algorithm" (Expand Search), "data packing 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: (((("develop cosine algorithm") OR ("elements data algorithm"))) OR ("data backing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop cosine algorithm\") OR (\"elements data algorithm\"))) OR (\"data backing algorithm\"))".
• Removing quotes may allow a broader search: (((( develop cosine algorithm ) OR ( elements data algorithm ))) OR ( data backing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop cosine algorithm") OR ("elements data algorithm"))) OR ("data backing algorithm"))*.
