Perhaps you should try some spelling variations:
"machinery counting methods algorithm" » "machinery using methods algorithm", "machinery nursing methods algorithm", "machinery control methods algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machinery counting methods algorithm") OR ("modified one approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machinery counting methods algorithm\") OR (\"modified one approximation algorithms\"))".
• Removing quotes may allow a broader search: (( machinery counting methods algorithm ) OR ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machinery counting methods algorithm") OR ("modified one approximation algorithms"))*.
