Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"image 1_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_single algorithm" (Expand Search)
"element rast algorithm" » "element best algorithm" (Expand Search), "element forest algorithm" (Expand Search), "element based algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "element ree 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 1_using algorithm") OR ("data processing algorithm"))) OR ("element rast algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"data processing algorithm\"))) OR (\"element rast algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( data processing algorithm ))) OR ( element rast algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("data processing algorithm"))) OR ("element rast algorithm"))*.
