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