Perhaps you should try some spelling variations:
"modified adaptive evolutionary algorithm" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified objective evolutionary algorithm"
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization 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 passive quantization algorithm") OR ("modified adaptive evolutionary algorithm"))~.
• Removing quotes may allow a broader search: (( modified passive quantization algorithm ) or ( modified adaptive evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithm") or ("modified adaptive evolutionary algorithm"))*.
