Perhaps you should try some spelling variations:
"modified objective optimisation algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithms", "modified multiobjective optimization algorithms"
"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"

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