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