Perhaps you should try some spelling variations:
"spatial modeling algorithm" » "spatial scheduling algorithm" (Expand Search), "statistical modeling algorithm" (Expand Search)
"data boosting algorithm" » "data cosine algorithm" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated 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 ("data boosting algorithm"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"spatial modeling algorithm\") OR (\"data boosting algorithm\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( spatial modeling algorithm ) OR ( data boosting algorithm ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("spatial modeling algorithm") OR ("data boosting algorithm"))) OR ("element update algorithm"))*.
