Perhaps you should try some spelling variations:
"modified based estimation algorithmss" » "modified based estimation algorithms", "modified based estimation algorithm", "modified based optimization algorithms", "modified pose estimation algorithmss", "modified based investigation algorithmss", "modified pulses estimation algorithmss", "modified male estimation algorithmss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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