Perhaps you should try some spelling variations:
"modified static optimization algorithmssss" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified stage optimization algorithmssss", "modified stochastic optimization algorithmssss", "modified staffing optimization algorithmssss"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified static optimization algorithmssss") OR ("modified parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified static optimization algorithmssss\") OR (\"modified parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified static optimization algorithmssss ) OR ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithmssss") OR ("modified parameters estimation algorithms"))*.
