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 fusion algorithm" » "element lasso algorithm" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh 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: (("post processing algorithm") OR ((("element erf algorithm") OR ("element fusion algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post processing algorithm\") OR (((\"element erf algorithm\") OR (\"element fusion algorithm\"))))".
• Removing quotes may allow a broader search: (( post processing algorithm ) OR ((( element erf algorithm ) OR ( element fusion algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("post processing algorithm") OR ((("element erf algorithm") OR ("element fusion algorithm"))))*.
