Perhaps you should try some spelling variations:
"modified parameters estimation algorithmssss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter estimation algorithmssss", "modified parameter estimates algorithmssss", "modified parameter optimization algorithmssss"
"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 static optimization algorithms") OR ("modified parameters estimation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified static optimization algorithms ) or ( modified parameters estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithms") or ("modified parameters estimation algorithmssss"))*.
