Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"when learning estimation algorithm" » "when learning emotion algorithm", "when lighting estimation algorithm", "deep learning estimation algorithm", "how learning estimation algorithm", "shot learning 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: (("when learning estimation algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("when learning estimation algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( when learning estimation algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("when learning estimation algorithm") or ("modified multiobjective optimized algorithm"))*.
