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)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element data 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 ("element te algorithm"))) OR ("waste processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"element te algorithm\"))) OR (\"waste processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( element te algorithm ))) OR ( waste processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("element te algorithm"))) OR ("waste processing algorithm"))*.
