Perhaps you should try some spelling variations:
"implement routine algorithms" » "implement cosine algorithm" (Expand Search), "implemented routine algorithms" (Expand Search), "implementing routine algorithms" (Expand Search)
"data using algorithms" » "data cosine algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data 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 routine algorithms") OR ("element data algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement routine algorithms\") OR (\"element data algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( implement routine algorithms ) OR ( element data algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("implement routine algorithms") OR ("element data algorithm"))) OR ("data using algorithms"))*.
