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