Perhaps you should try some spelling variations:
"modified robust estimation algorithms" » "modified robust estimation algorithm", "modified robust optimization algorithms", "modified robust optimisation algorithm", "modified pose estimation algorithms", "modified risk estimation algorithms"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

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 learning method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified robust estimation algorithms") OR ("modified learning method algorithm")).
• Removing quotes may allow a broader search: (( modified robust estimation algorithms ) or ( modified learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified robust estimation algorithms") or ("modified learning method algorithm"))*.
