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