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