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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified quantile estimation algorithmss\") OR (\"modified parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified quantile estimation algorithmss ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile estimation algorithmss") OR ("modified parameters optimization algorithms"))*.
