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)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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), "recent 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: (("image routing algorithm") OR ((("movement data algorithm") OR ("element data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image routing algorithm\") OR (((\"movement data algorithm\") OR (\"element data algorithm\"))))".
• Removing quotes may allow a broader search: (( image routing algorithm ) OR ((( movement data algorithm ) OR ( element data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image routing algorithm") OR ((("movement data algorithm") OR ("element data algorithm"))))*.
