Perhaps you should try some spelling variations:
"modified adaptive estimation algorithmss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithmss", "modified quantile estimation algorithmss", "modified adaptive quantization algorithmss", "modified passive estimation algorithmss"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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 objective solution algorithm") OR ("modified adaptive estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified adaptive estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified adaptive estimation algorithmss"))*.
