Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified quantile approximation algorithms" » "modified time approximation algorithms", "modified diophantine approximation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimization algorithms") or ("modified quantile approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive optimization algorithms") OR ("modified quantile approximation algorithms"))*.
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) or ( modified quantile approximation algorithms ))*.
