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