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)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("present data algorithm") OR ("relevant data algorithm"))) OR ("image routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present data algorithm\") OR (\"relevant data algorithm\"))) OR (\"image routing algorithm\"))".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( relevant data algorithm ))) OR ( image routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present data algorithm") OR ("relevant data algorithm"))) OR ("image routing algorithm"))*.
