Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"

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