Perhaps you should try some spelling variations:
"elements under algorithm" » "elements new algorithm" (Expand Search), "elements tide algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements tended algorithm" (Expand Search)
"time processing algorithm" » "image processing algorithm" (Expand Search), "pre processing algorithm" (Expand Search), "antigen processing algorithm" (Expand Search)
"element forest algorithm" » "element ore 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 forest algorithm") OR ("elements under algorithm"))) OR ("time processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"elements under algorithm\"))) OR (\"time processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( elements under algorithm ))) OR ( time processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("elements under algorithm"))) OR ("time processing algorithm"))*.
