Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"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"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithm") or ("verified network optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithm") OR ("verified network optimization algorithms")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( verified network optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("verified network optimization algorithms"))*.
