Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"relevant pfos algorithm" » "relevant pso algorithm" (Expand Search), "relevant ppo algorithm" (Expand Search), "relevant pass algorithm" (Expand Search), "relevant non algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement 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: (((("relevant pfos algorithm") OR ("element data algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant pfos algorithm\") OR (\"element data algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant pfos algorithm ) OR ( element data algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant pfos algorithm") OR ("element data algorithm"))) OR ("implement routine algorithm"))*.
