Perhaps you should try some spelling variations:
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation algorithm"
"modified charging optimized algorithm" » "modified charging optimized algorithms", "modified charging optimizer algorithms", "modified choosing optimizer algorithm", "modified caging optimized algorithm", "modified carbon optimized 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 charging optimized algorithm") OR ("modified time approximation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified charging optimized algorithm\") OR (\"modified time approximation algorithm\"))".
• Removing quotes may allow a broader search: (( modified charging optimized algorithm ) OR ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimized algorithm") OR ("modified time approximation algorithm"))*.
