Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified network optimization algorithm"
"modified robust estimation algorithms" » "modified robust estimation algorithm", "modified robust optimization algorithms", "modified robust approximation algorithms", "modified pose estimation algorithms", "modified risk estimation 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 robust estimation algorithms") or ("modified notion optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified robust estimation algorithms") OR ("modified notion optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( modified robust estimation algorithms ) or ( modified notion optimisation algorithm ))*.
