Perhaps you should try some spelling variations:
"modified oxygen solution algorithm" » "modified oxygen evolution algorithm", "modified oxygen convolution algorithms", "modified oxygen evolutionary algorithm", "modified oxygen saturation algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation 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 network approximation algorithms") OR ("modified oxygen solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified network approximation algorithms ) or ( modified oxygen solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network approximation algorithms") or ("modified oxygen solution algorithm"))*.
