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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified cliff predation algorithm\") OR (\"modified multiobjective optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified cliff predation algorithm ) OR ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified cliff predation algorithm") OR ("modified multiobjective optimized algorithm"))*.
