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