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 data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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 modeling algorithm") OR ("image processing algorithm"))) OR ("element data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post modeling algorithm\") OR (\"image processing algorithm\"))) OR (\"element data algorithms\"))".
• Removing quotes may allow a broader search: (((( post modeling algorithm ) OR ( image processing algorithm ))) OR ( element data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("post modeling algorithm") OR ("image processing algorithm"))) OR ("element data algorithms"))*.
