Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified passive quantization algorithmsss" » "modified adaptive quantization algorithmsss", "modified passive quantization algorithm", "modified passive quantization algorithmic"

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 objective convolution algorithms") OR ("modified passive quantization algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified passive quantization algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("modified passive quantization algorithmsss"))*.
