Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified total predation algorithm" » "modified total predators algorithm", "modified total estimation algorithm", "modified thermal predation algorithm", "modified ti6al4v predation algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified total predation algorithm") OR ("modified multiobjective optimized algorithm"))~.
• Removing quotes may allow a broader search: (( modified total predation algorithm ) or ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified total predation algorithm") or ("modified multiobjective optimized algorithm"))*.
