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