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