Perhaps you should try some spelling variations:
"image 1_routing algorithms" » "image routing algorithm" (Expand Search), "image sorting algorithms" (Expand Search), "image performing algorithms" (Expand Search), "image 1_resting algorithms" (Expand Search), "image 1_reducing algorithms" (Expand Search), "image 1_using algorithms" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (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: (((("image 1_routing algorithms") OR ("data using algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_routing algorithms\") OR (\"data using algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_routing algorithms ) OR ( data using algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_routing algorithms") OR ("data using algorithm"))) OR ("relevant data algorithm"))*.
