Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"data models algorithm" » "data modeling algorithm" (Expand Search), "data novel algorithm" (Expand Search), "data modbo algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (("data models algorithm") OR ((("experiments based algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data models algorithm\") OR (((\"experiments based algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( data models algorithm ) OR ((( experiments based algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data models algorithm") OR ((("experiments based algorithm") OR ("element method algorithm"))))*.
