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