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