Perhaps you should try some spelling variations:
"modified parameter optimization algorithmsss" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter optimisation algorithmss", "modified parameter estimation algorithmsss", "modified parameter estimation algorithmss", "modified parameters optimization algorithmsss"
"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 static optimization algorithms") OR ("modified parameter optimization algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified static optimization algorithms\") OR (\"modified parameter optimization algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified static optimization algorithms ) OR ( modified parameter optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithms") OR ("modified parameter optimization algorithmsss"))*.
