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