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