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 network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"

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