Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search), "implemented routine algorithm" (Expand Search), "implementing routine algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search)
"elements b algorithm" » "elements _ algorithms" (Expand Search), "elements rd algorithm" (Expand Search), "elements _ 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 ((("elements b algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routine algorithm\") OR (((\"elements b algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( implement routine algorithm ) OR ((( elements b algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement routine algorithm") OR ((("elements b algorithm") OR ("element method algorithm"))))*.
