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