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