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