Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"machines learning estimation algorithm" » "machines learning emotion algorithm", "machines lighting estimation algorithm", "machine learning estimation algorithm", "active learning estimation algorithm", "mapping learning estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machines learning estimation algorithm") or ("modified notion approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines learning estimation algorithm") OR ("modified notion approximation algorithms")).
• Removing quotes may allow a broader search: (( machines learning estimation algorithm ) or ( modified notion approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines learning estimation algorithm") or ("modified notion approximation algorithms"))*.
