Perhaps you should try some spelling variations:
"modified thermal approximation algorithm" » "modified thermal approximation algorithms", "modified average approximation algorithm", "modified thermal oxidation algorithm", "modified time approximation algorithm"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 objective allocation algorithm") or ("modified thermal approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective allocation algorithm") OR ("modified thermal approximation algorithm")).
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) or ( modified thermal approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") or ("modified thermal approximation algorithm"))*.
