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)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "element ore algorithm" (Expand Search), "elements over 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: (((("data modeling algorithm") OR ("image processing algorithm"))) OR ("element novel algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"image processing algorithm\"))) OR (\"element novel algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( image processing algorithm ))) OR ( element novel algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("image processing algorithm"))) OR ("element novel algorithm"))*.
