Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter optimized algorithms", "modified parameters optimization algorithms"
"modified df estimation algorithms" » "modified df estimation algorithm", "modified df optimisation algorithm", "modified df approximation algorithms", "modified _ estimation algorithms", "modified adam estimation algorithms", "modified bi1 estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df estimation algorithms") or ("modified parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df estimation algorithms") OR ("modified parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( modified df estimation algorithms ) or ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df estimation algorithms") or ("modified parameter optimization algorithms"))*.
