Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified thermal approximation algorithms" » "modified average approximation algorithms", "modified thermal oxidation algorithms", "modified time approximation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimized algorithm") or ("modified thermal approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("modified thermal approximation algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified thermal approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("modified thermal approximation algorithms"))*.
