Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified robust estimation algorithms" » "modified robust estimation algorithm", "modified robust optimization algorithms", "modified robust optimisation algorithm", "modified pose estimation algorithms", "modified risk estimation 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 algorithm") or ("modified robust estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("modified robust estimation algorithms"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( modified robust estimation algorithms ))*.
