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)
"level using algorithm" » "level using algorithms" (Expand Search), "level routing algorithm" (Expand Search), "level fusion algorithm" (Expand Search), "levels using algorithm" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 each algorithm") OR ((("implement routine algorithm") OR ("level using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element each algorithm\") OR (((\"implement routine algorithm\") OR (\"level using algorithm\"))))".
• Removing quotes may allow a broader search: (( element each algorithm ) OR ((( implement routine algorithm ) OR ( level using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element each algorithm") OR ((("implement routine algorithm") OR ("level using algorithm"))))*.
