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