Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive optimization algorithms"

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 multiobjective optimized algorithms") OR ("modified passive optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( modified passive optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") or ("modified passive optimization algorithms"))*.
