Perhaps you should try some spelling variations:
"element based algorithms" » "element based algorithm" (Expand Search)
"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)

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