Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"image 2_long algorithm" » "image colony algorithm" (Expand Search), "image making algorithm" (Expand Search), "image mining algorithm" (Expand Search), "image 1_long algorithm" (Expand Search), "image 2_an 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: (("elements method algorithm") OR ((("data using algorithm") OR ("image 2_long algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data using algorithm\") OR (\"image 2_long algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data using algorithm ) OR ( image 2_long algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data using algorithm") OR ("image 2_long algorithm"))))*.
