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