Perhaps you should try some spelling variations:
"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"
"modified adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution algorithms"

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