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 erf algorithm" » "element rf algorithm" (Expand Search), "element em algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"element lr algorithm" » "element mlm algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ore algorithm" (Expand Search), "elements zr 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 lr algorithm") OR ("element erf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"waste processing algorithm\") OR (((\"element lr algorithm\") OR (\"element erf algorithm\"))))".
• Removing quotes may allow a broader search: (( waste processing algorithm ) OR ((( element lr algorithm ) OR ( element erf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("waste processing algorithm") OR ((("element lr algorithm") OR ("element erf algorithm"))))*.
