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 mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element te algorithms" (Expand Search), "element g algorithms" (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 ml algorithms") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"plant processing algorithm\") OR (((\"element ml algorithms\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( plant processing algorithm ) OR ((( element ml algorithms ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("plant processing algorithm") OR ((("element ml algorithms") OR ("element mesh algorithm"))))*.
