Perhaps you should try some spelling variations:
"modified bi1 approximation algorithm" » "modified bi1 approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified one approximation algorithm"
"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"

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 adaptive estimation algorithms") OR ("modified bi1 approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithms ) or ( modified bi1 approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithms") or ("modified bi1 approximation algorithm"))*.
