Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified based estimation algorithmss" » "modified based estimation algorithms", "modified based estimation algorithm", "modified pose estimation algorithmss", "modified based investigation algorithmss", "modified pulses estimation algorithmss", "modified male estimation algorithmss"

You may be able to get more results by adjusting your search query.

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