Perhaps you should try some spelling variations:
"verified network optimization algorithms" » "verified network optimisation algorithm", "verified network estimation algorithms", "verified network estimation algorithm", "verified network optimisation algorithms", "verified network estimation algorithmss", "certified network optimization algorithms", "defined network optimization algorithms"
"modified parameter optimization algorithm" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter estimation algorithms", "modified parameters optimization algorithm"

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 parameter optimization algorithm") OR ("verified network optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( verified network optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") or ("verified network optimization algorithms"))*.
