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 caging emotion algorithm" » "modified caging evolution algorithm", "modified caging estimation algorithm", "modified caging predation algorithm", "modified learning emotion 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 adaptive quantization algorithms") OR ("modified caging emotion algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithms ) or ( modified caging emotion algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithms") or ("modified caging emotion algorithm"))*.
