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