Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified charging predation algorithm" » "modified charging predators algorithm", "modified charging estimation algorithm", "modified charging station algorithm", "modified caging predation algorithm", "modified carbon predation 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 charging predation algorithm\") OR (\"modified multiobjective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified charging predation algorithm ) OR ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging predation algorithm") OR ("modified multiobjective optimized algorithms"))*.
