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)
"element multi algorithm" » "element multiple algorithms" (Expand Search), "element custom 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 multi algorithm") OR ("element method algorithm"))) OR ("post processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element multi algorithm\") OR (\"element method algorithm\"))) OR (\"post processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element multi algorithm ) OR ( element method algorithm ))) OR ( post processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element multi algorithm") OR ("element method algorithm"))) OR ("post processing algorithm"))*.
