Perhaps you should try some spelling variations:
"modified thermal compositions algorithms" » "modified thermal decomposition algorithm", "modified thermal convolution algorithms", "modified chemical compositions algorithms"
"modified coverage approximation algorithms" » "modified average approximation algorithms"

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