Perhaps you should try some spelling variations:
"modified adaptive quantization algorithms" » "modified adaptive estimation algorithms", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithms", "modified passive quantization algorithms"
"modified parameter optimizer algorithmss" » "modified parameter optimizer algorithms", "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimization algorithmss"

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 quantization algorithms") or ("modified parameter optimizer algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive quantization algorithms") OR ("modified parameter optimizer algorithmss"))*.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithms ) or ( modified parameter optimizer algorithmss ))*.
