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

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: (("modified thermal solution algorithm") OR ("modified coverage approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified thermal solution algorithm ) or ( modified coverage approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified thermal solution algorithm") or ("modified coverage approximation algorithms"))*.
