Perhaps you should try some spelling variations:
"image boosting algorithm" » "image routing algorithm" (Expand Search), "image twisting algorithm" (Expand Search), "image hastings algorithm" (Expand Search)
"case modeling algorithm" » "case making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "a modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("image boosting algorithm") OR ("case modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image boosting algorithm\") OR (\"case modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( image boosting algorithm ) OR ( case modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image boosting algorithm") OR ("case modeling algorithm"))) OR ("element method algorithm"))*.
