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 static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing 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 static optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithmss") OR ("modified static optimization algorithms")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithmss ) or ( modified static optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithmss") or ("modified static optimization algorithms"))*.
