Perhaps you should try some spelling variations:
"post processing algorithm" » "waste processing algorithm" (Expand Search), "food processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search)
"element forest algorithm" » "element ore algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present each algorithm" (Expand Search), "patient data 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: "((((\"element forest algorithm\") OR (\"present data algorithm\"))) OR (\"post processing algorithm\"))~".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( present data algorithm ))) OR ( post processing algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("present data algorithm"))) OR ("post processing algorithm"))*.
