Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"element study algorithm" » "element wsindy algorithm" (Expand Search), "element td3 algorithm" (Expand Search), "element seu algorithm" (Expand Search), "relevant study algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent study 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: (((("element study algorithm") OR ("element data algorithm"))) OR ("implement routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element study algorithm\") OR (\"element data algorithm\"))) OR (\"implement routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element study algorithm ) OR ( element data algorithm ))) OR ( implement routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element study algorithm") OR ("element data algorithm"))) OR ("implement routing algorithm"))*.
