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)
"element mesh algorithms" » "element best algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element best algorithm" (Expand Search), "element method algorithms" (Expand Search), "elements mges algorithms" (Expand Search), "element te algorithms" (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 ("element mesh algorithms"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"element mesh algorithms\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( element mesh algorithms ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("element mesh algorithms"))) OR ("implement routine algorithm"))*.
