Perhaps you should try some spelling variations:
"modified rough approximations algorithms" » "modified rough approximation algorithms", "modified rough approximation algorithm", "modified one approximation algorithms"
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized 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 rough approximations algorithms") OR ("modified multiobjective optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified rough approximations algorithms ) or ( modified multiobjective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified rough approximations algorithms") or ("modified multiobjective optimizer algorithms"))*.
