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