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 adaptive quantization algorithmss", "modified static optimization algorithmss", "modified passive optimization algorithmss"
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"

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

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