Perhaps you should try some spelling variations:
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case 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 data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("experiments based algorithm") OR ("element data algorithm"))) OR ("image 1_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithm\") OR (\"element data algorithm\"))) OR (\"image 1_using algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithm ) OR ( element data algorithm ))) OR ( image 1_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithm") OR ("element data algorithm"))) OR ("image 1_using algorithm"))*.
