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