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