Perhaps you should try some spelling variations:
"post processing algorithm" » "post processing algorithms" (Expand Search), "text processing algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"data could algorithm" » "data mould algorithm" (Expand Search), "data carlo algorithm" (Expand Search), "data colony 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: (((("data could algorithm") OR ("post processing algorithm"))) OR ("elements method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data could algorithm\") OR (\"post processing algorithm\"))) OR (\"elements method algorithm\"))".
• Removing quotes may allow a broader search: (((( data could algorithm ) OR ( post processing algorithm ))) OR ( elements method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data could algorithm") OR ("post processing algorithm"))) OR ("elements method algorithm"))*.
