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