Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"

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: (("modified adaptive optimization algorithms") or ("modified parameters optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified parameters optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified parameters optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") or ("modified parameters optimization algorithmss"))*.
