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