Perhaps you should try some spelling variations:
"spatial modeling algorithm" » "spatial making algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element based algorithm" » "engagement based 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: (("spatial modeling algorithm") OR ((("relevant data algorithms") OR ("element based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"spatial modeling algorithm\") OR (((\"relevant data algorithms\") OR (\"element based algorithm\"))))".
• Removing quotes may allow a broader search: (( spatial modeling algorithm ) OR ((( relevant data algorithms ) OR ( element based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("spatial modeling algorithm") OR ((("relevant data algorithms") OR ("element based algorithm"))))*.
