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