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 tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"client needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "urgent needs algorithm" (Expand Search), "china needs 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 tree algorithms") OR ("implement routine algorithm"))) OR ("client needs algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element tree algorithms\") OR (\"implement routine algorithm\"))) OR (\"client needs algorithm\"))".
• Removing quotes may allow a broader search: (((( element tree algorithms ) OR ( implement routine algorithm ))) OR ( client needs algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element tree algorithms") OR ("implement routine algorithm"))) OR ("client needs algorithm"))*.
