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

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