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