Perhaps you should try some spelling variations:
"modified adaptive optimization algorithmss" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithmss", "modified adaptive quantization algorithmss", "modified static optimization algorithmss", "modified passive optimization algorithmss"
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation 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 algorithmss") or ("modified parameters optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithmss") OR ("modified parameters optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithmss ) or ( modified parameters optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithmss") or ("modified parameters optimisation algorithm"))*.
