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