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