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