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)
"tests using algorithms" » "tests pacing algorithms" (Expand Search), "tests nine algorithms" (Expand Search), "tests sorting algorithms" (Expand Search), "tests routing algorithms" (Expand Search), "tests fusion algorithms" (Expand Search), "tests making algorithms" (Expand Search), "tested using algorithms" (Expand Search), "results using algorithms" (Expand Search)
"data using algorithm" » "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search), "data making 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 ("tests using algorithms"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"tests using algorithms\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( tests using algorithms ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("tests using algorithms"))) OR ("data using algorithm"))*.
