Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"modified stochastic optimized algorithm" » "modified stochastic optimization algorithm", "modified stochastic optimized algorithms", "modified stochastic optimizer 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 optimization algorithm") OR ("modified stochastic optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified stochastic optimized algorithm\"))*".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified stochastic optimized algorithm ))*.
