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