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 data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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 data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data models algorithm\") OR (((\"experiments based algorithm\") OR (\"element data algorithms\"))))".
• Removing quotes may allow a broader search: (( data models algorithm ) OR ((( experiments based algorithm ) OR ( element data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data models algorithm") OR ((("experiments based algorithm") OR ("element data algorithms"))))*.
