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