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

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