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

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