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)
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (((("based modeling algorithm") OR ("image processing algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"based modeling algorithm\") OR (\"image processing algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( based modeling algorithm ) OR ( image processing algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("based modeling algorithm") OR ("image processing algorithm"))) OR ("relevant data algorithm"))*.
