Perhaps you should try some spelling variations:
"modified objective approximation algorithm" » "modified objective approximation algorithms"
"modified thermal evolution algorithm" » "modified thermal solution algorithm", "modified thermal evolutionary algorithm", "modified thermal convolution algorithms", "modified thermal evaporation algorithm", "modified thermal regulation 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 evolution algorithm") OR ("modified objective approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified thermal evolution algorithm ) or ( modified objective approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified thermal evolution algorithm") or ("modified objective approximation algorithm"))*.
