Perhaps you should try some spelling variations:
"image 1_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 1_resting algorithm" (Expand Search), "image 1_reducing algorithm" (Expand Search), "image 1_using algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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 data algorithms") OR ((("data using algorithm") OR ("image 1_routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithms\") OR (((\"data using algorithm\") OR (\"image 1_routing algorithm\"))))".
• Removing quotes may allow a broader search: (( element data algorithms ) OR ((( data using algorithm ) OR ( image 1_routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithms") OR ((("data using algorithm") OR ("image 1_routing algorithm"))))*.
