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 both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh 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: (((("image 1_using algorithm") OR ("data processing algorithm"))) OR ("element both algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"data processing algorithm\"))) OR (\"element both algorithms\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( data processing algorithm ))) OR ( element both algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("data processing algorithm"))) OR ("element both algorithms"))*.
