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