Perhaps you should try some spelling variations:
"experiments based algorithms" » "experiments showed algorithms" (Expand Search), "experimental basis algorithms" (Expand Search), "experimental case algorithms" (Expand Search), "experiments based algorithm" (Expand Search)
"image routing algorithm" » "image modeling algorithm" (Expand Search), "image finding algorithm" (Expand Search), "image making algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 3_using 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 algorithms") OR ("element data algorithm"))) OR ("image routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments based algorithms\") OR (\"element data algorithm\"))) OR (\"image routing algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments based algorithms ) OR ( element data algorithm ))) OR ( image routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments based algorithms") OR ("element data algorithm"))) OR ("image routing algorithm"))*.
