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