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