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