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