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

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