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