Perhaps you should try some spelling variations:
"plant processing algorithm" » "post processing algorithm" (Expand Search), "image processing algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"element forest algorithm" » "element ore algorithm" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element em algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 ("element each algorithm"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"element each algorithm\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( element each algorithm ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("element each algorithm"))) OR ("plant processing algorithm"))*.
