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