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