Perhaps you should try some spelling variations:
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile optimized algorithms", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"
"modified orca estimation algorithm" » "modified dorca estimation algorithm", "modified orcad estimation algorithm", "modified ohca estimation algorithm"

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