Perhaps you should try some spelling variations:
"image 2_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (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)
"based model algorithm" » "based novel algorithm" (Expand Search), "based modbo algorithm" (Expand Search), "based modeling 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: (("element method algorithm") OR ((("image 2_using algorithm") OR ("based model algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image 2_using algorithm\") OR (\"based model algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image 2_using algorithm ) OR ( based model algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image 2_using algorithm") OR ("based model algorithm"))))*.
