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 quantization algorithms" » "modified passive estimation algorithms", "modified passive optimization algorithms", "modified adaptive quantization algorithms"

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 algorithms") or ("modified passive quantization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithms") OR ("modified passive quantization algorithms"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( modified passive quantization algorithms ))*.
