Perhaps you should try some spelling variations:
"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)
"data using algorithm" » "data using algorithms" (Expand Search), "data fusion algorithm" (Expand Search), "data making 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: (((("data using algorithm") OR ("image routing algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"image routing algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( image routing algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("image routing algorithm"))) OR ("element data algorithm"))*.
