Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified flour solution algorithm" » "modified flour evolution algorithm", "modified flour convolution algorithms", "modified flour evolutionary algorithm", "modified four solution algorithm", "modified floor solution algorithm", "modified flor solution algorithm"

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 algorithm"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) or ( modified flour solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithms") or ("modified flour solution algorithm"))*.
