Perhaps you should try some spelling variations:
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms", "modified passive estimation algorithms"
"modified control method algorithm" » "mode control method algorithm", "modified control mom algorithm", "modified control methods 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 control method algorithm") OR ("modified adaptive estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified control method algorithm ) or ( modified adaptive estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified control method algorithm") or ("modified adaptive estimation algorithms"))*.
