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

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

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