Perhaps you should try some spelling variations:
"post processing algorithm" » "post processing algorithms" (Expand Search), "text processing algorithm" (Expand Search)
"data making algorithm" » "data cosine algorithm" (Expand Search), "data mining algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post processing algorithm\") OR (\"data making algorithm\"))) OR (\"elements method algorithm\"))~".
• Removing quotes may allow a broader search: (((( post processing algorithm ) OR ( data making algorithm ))) OR ( elements method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("post processing algorithm") OR ("data making algorithm"))) OR ("elements method algorithm"))*.
