Perhaps you should try some spelling variations:
"case learning method algorithm" » "case learning mom algorithm", "case learning methods algorithm", "case graining methods algorithm", "case learning emotion algorithm", "based learning method algorithm", "a learning method 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: (("case learning method algorithm") OR ("modified network approximation algorithms"))~.
• Removing quotes may allow a broader search: (( case learning method algorithm ) or ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("case learning method algorithm") or ("modified network approximation algorithms"))*.
