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