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