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