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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 using algorithm") OR ("post processing algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"post processing algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( post processing algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("post processing algorithm"))) OR ("relevant data algorithm"))*.
