Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified flour solution algorithms" » "modified flour solution algorithm", "modified flour evolution algorithm", "modified flour convolution algorithms", "modified four solution algorithms", "modified floor solution algorithms", "modified flor solution 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 coverage approximation algorithms") OR ("modified flour solution algorithms"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) or ( modified flour solution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithms") or ("modified flour solution algorithms"))*.
