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