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 allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"

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

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