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