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

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