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