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