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