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