Perhaps you should try some spelling variations:
"tests routing algorithm" » "tests modeling algorithm" (Expand Search), "tests finding algorithm" (Expand Search), "tests making algorithm" (Expand Search), "tests using algorithm" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"effects using algorithm" » "effects using algorithms" (Expand Search), "effects fusion algorithm" (Expand Search), "effects making algorithm" (Expand Search), "events using 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 routing algorithm") OR ("effects using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"tests routing algorithm\") OR (\"effects using algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( tests routing algorithm ) OR ( effects using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("tests routing algorithm") OR ("effects using algorithm"))))*.
