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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified static optimization algorithms\") OR (\"modified parameter optimization algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified static optimization algorithms ) OR ( modified parameter optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithms") OR ("modified parameter optimization algorithmss"))*.
