Perhaps you should try some spelling variations:
"image 2_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 2_resting algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 2_targeting algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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: (("movement data algorithm") OR ((("data using algorithm") OR ("image 2_routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement data algorithm\") OR (((\"data using algorithm\") OR (\"image 2_routing algorithm\"))))".
• Removing quotes may allow a broader search: (( movement data algorithm ) OR ((( data using algorithm ) OR ( image 2_routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement data algorithm") OR ((("data using algorithm") OR ("image 2_routing algorithm"))))*.
