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