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