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