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