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)
"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: (((("image 1_routing algorithm") OR ("data using algorithm"))) OR ("movement data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_routing algorithm\") OR (\"data using algorithm\"))) OR (\"movement data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_routing algorithm ) OR ( data using algorithm ))) OR ( movement data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_routing algorithm") OR ("data using algorithm"))) OR ("movement data algorithm"))*.
