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