Perhaps you should try some spelling variations:
"modified network optimization algorithms" » "modified network optimisation algorithm", "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimisation algorithms", "modified network estimation algorithmss", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization algorithms"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation 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 network optimization algorithms") or ("modified parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithms") OR ("modified parameters optimization algorithm"))*.
• Removing quotes may allow a broader search: (( modified network optimization algorithms ) or ( modified parameters optimization algorithm ))*.
