Perhaps you should try some spelling variations:
"fragment based algorithm" » "agent based algorithm" (Expand Search), "gradient based algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data algorithm" (Expand Search)
"element mapping algorithm" » "elements mapping algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("fragment based algorithm") OR ("element data algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fragment based algorithm\") OR (\"element data algorithm\"))) OR (\"element mapping algorithm\"))*".
• Removing quotes may allow a broader search: (((( fragment based algorithm ) OR ( element data algorithm ))) OR ( element mapping algorithm ))*.
