Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified orca estimation algorithms" » "modified orca estimation algorithm", "modified orca optimization algorithms", "modified orca optimisation algorithm", "modified dorca estimation algorithms", "modified orcad estimation algorithms", "modified ohca estimation 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 orca estimation algorithms") OR ("modified adaptive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified orca estimation algorithms ) or ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified orca estimation algorithms") or ("modified adaptive quantization algorithm"))*.
