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