Perhaps you should try some spelling variations:
"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"
"modified caging mppt algorithm" » "modified caging mom algorithm", "modified caging qspr algorithm", "modified aging mppt algorithm", "modified changing mppt algorithm", "modified charging mppt algorithm"

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

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