Perhaps you should try some spelling variations:
"waste processing algorithm" » "waste routing algorithm" (Expand Search), "waste tracking algorithm" (Expand Search), "waste boosting algorithm" (Expand Search), "data processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 ("data modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"waste processing algorithm\") OR (\"data modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( waste processing algorithm ) OR ( data modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("waste processing algorithm") OR ("data modeling algorithm"))) OR ("element method algorithm"))*.
