Perhaps you should try some spelling variations:
"certified network optimization algorithms" » "certified network optimisation algorithm", "certified network estimation algorithms", "certified network estimation algorithm", "verified network optimization algorithms"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive convolution algorithms") or ("certified network optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive convolution algorithms") OR ("certified network optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) or ( certified network optimization algorithms ))*.
