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