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)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 based algorithm") OR ("movement data algorithm"))) OR ("implement routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"movement data algorithm\"))) OR (\"implement routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( movement data algorithm ))) OR ( implement routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("movement data algorithm"))) OR ("implement routing algorithm"))*.
