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

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