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 algorithms" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter 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 parameter optimizer algorithms") OR ("modified adaptive quantization algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithms ) or ( modified adaptive quantization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimizer algorithms") or ("modified adaptive quantization algorithms"))*.
