Perhaps you should try some spelling variations:
"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"
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters 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 optimisation algorithms") or ("modified parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithms") OR ("modified parameter optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified static optimisation algorithms ) or ( modified parameter optimization algorithms ))*.
