Perhaps you should try some spelling variations:
"image 3_routing algorithms" » "image routing algorithm" (Expand Search), "image sorting algorithms" (Expand Search), "image performing algorithms" (Expand Search), "image 3_resting algorithms" (Expand Search), "image 3_using algorithms" (Expand Search), "image 3_targeting algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (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: (("element method algorithm") OR ((("data using algorithms") OR ("image 3_routing algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data using algorithms\") OR (\"image 3_routing algorithms\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data using algorithms ) OR ( image 3_routing algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data using algorithms") OR ("image 3_routing algorithms"))))*.
