Perhaps you should try some spelling variations:
"image 2_using algorithms" » "image using algorithms" (Expand Search), "image routing algorithm" (Expand Search), "image sorting algorithms" (Expand Search), "image 2_using algorithmss" (Expand Search), "image 2_routing algorithms" (Expand Search), "image 2_fusion algorithms" (Expand Search), "image 1_using algorithms" (Expand Search), "image 2_single algorithms" (Expand Search), "image 2_long algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("data using algorithm") OR ("image 2_using algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"image 2_using algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( image 2_using algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("image 2_using algorithms"))) OR ("element method algorithm"))*.
