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 optimisation algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimization algorithms", "modified stage optimization algorithms", "modified stochastic optimization algorithms"

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

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