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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified robust optimization algorithm") or ("modified parameter optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified robust optimization algorithm") OR ("modified parameter optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified robust optimization algorithm ) or ( modified parameter optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified robust optimization algorithm") or ("modified parameter optimization algorithmss"))*.
