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

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