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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element mlm algorithm" » "element em algorithm" (Expand Search), "element svm algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "elements ppm 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 mlm algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"plant processing algorithm\") OR (((\"element mlm algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( plant processing algorithm ) OR ((( element mlm algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("plant processing algorithm") OR ((("element mlm algorithm") OR ("element method algorithm"))))*.
