Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent 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: (((("relevant data algorithm") OR ("present data algorithm"))) OR ("based modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"present data algorithm\"))) OR (\"based modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( present data algorithm ))) OR ( based modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("present data algorithm"))) OR ("based modeling algorithm"))*.
