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