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