Perhaps you should try some spelling variations:
"modified multiobjective approximation algorithms" » "modified multiobjective optimization algorithms"
"modified male optimization algorithm" » "modified male optimization algorithms", "modified male optimisation algorithm", "modified male estimation algorithm", "modified game optimization algorithm", "modified market optimization algorithm", "modified stage optimization 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 male optimization algorithm") OR ("modified multiobjective approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified male optimization algorithm ) or ( modified multiobjective approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified male optimization algorithm") or ("modified multiobjective approximation algorithms"))*.
