Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified minimal solution algorithms" » "modified minimal solution algorithm", "modified minimal evolution algorithm", "modified minimal convolution algorithms", "modified thermal solution algorithms", "modified optimal solution algorithms", "modified nodal solution algorithms"

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

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