Perhaps you should try some spelling variations:
"image 2_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (Expand Search)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (Expand Search)
"element based algorithm" » "engagement based 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: (((("element based algorithm") OR ("present data algorithms"))) OR ("image 2_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"present data algorithms\"))) OR (\"image 2_using algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( present data algorithms ))) OR ( image 2_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("present data algorithms"))) OR ("image 2_using algorithm"))*.
