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