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 both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element te algorithms" (Expand Search), "element mesh algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element de algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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 both algorithms") OR ("element data algorithms"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element both algorithms\") OR (\"element data algorithms\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element both algorithms ) OR ( element data algorithms ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element both algorithms") OR ("element data algorithms"))) OR ("implement routine algorithm"))*.
