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)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements other algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (Expand Search)
"element means algorithm" » "element search 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: (((("elements tree algorithms") OR ("element means algorithm"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements tree algorithms\") OR (\"element means algorithm\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements tree algorithms ) OR ( element means algorithm ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements tree algorithms") OR ("element means algorithm"))) OR ("plant processing algorithm"))*.
