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