Perhaps you should try some spelling variations:
"waste processing algorithm" » "data processing algorithm" (Expand Search), "image processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search)
"element forest algorithm" » "element ore 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)

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