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)
"fluent search algorithm" » "effluent search algorithm" (Expand Search), "fluent research 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: (((("fragment based algorithm") OR ("element data algorithm"))) OR ("fluent search algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fragment based algorithm\") OR (\"element data algorithm\"))) OR (\"fluent search algorithm\"))".
• Removing quotes may allow a broader search: (((( fragment based algorithm ) OR ( element data algorithm ))) OR ( fluent search algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("fragment based algorithm") OR ("element data algorithm"))) OR ("fluent search algorithm"))*.
